Question 4.
Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it.
Answer:
Frictional force is acting opposite to the movement of book i.e. upwards.

Question 5.
You spill a bucket of soapy water on a marble floor accidently. Would it make it easier or more difficult for you to walk on the floor? Why?
Answer:
It is difficult to walk on a soapy floor because layer of soap makes floor smooth. The coating of soap reduces the friction and the foot cannot make a proper grip on the floor and it starts getting to slip on the floor.

Question 6.
Explain why sportsmen use shoes with spikes.
Answer:
Sportsmen use shoes with spike to increase the friction so, that their shoes do not slip while they run or play.

Question 7.
Iqbal has to push a lighter box and Seema has to push a similar heavier box on the same floor. Who will have to apply a larger force and why?
Answer:
Seema will experience more frictional force because heavy object will be pressed hard against the opposite surface and produces more friction.

Question 8.
Explain why sliding friction less than static friction.
Answer:
Sliding friction is always less than static friction because two sliding objects find less time to get interlocked against, each others, irregularities of surfaces so they get less friction.

Question 9.
Give examples to show that friction is both a friend and a foe.
Answer:
Friction is a friend because :

• It allows us to walk comfortably on ground.
• It allows us to grip and catch different objects.
• Things don’t move from their places because of friction.
• Speeds of moving objects can be minimized or stopped by friction only.

Friction is foe because :

• It causes wear and tear in objects of our daily use and machines we use.
• Regular maintenance of objects moving against each other (machines and tools) wastes a lot of useful money.
• It makes the movement of heavy objects very difficult.
• It does not allow the regular free movement of substances.

Question 10.
Explain why objects moving in fluids must have special shapes.
Answer:
Objects moving in fluids must have a special shape called steamlined shape. Streamlined shape is that shape which overcomes the friction of fluid. They have pointed fronts with little broader middle portion which gets tapered at the back.

Answer:
When a body rolls on other body.

Short Answer Type Questions

Question 1.
What is friction?
Answer:
Friction is a force which comes in play when two -bodies move on each other. Friction works in opposite direction to the direction of the movement of objects.

Question 2.
What causes friction?
Answer:
Friction occurs when two bodies move on each other. Each surface has some irregularities on it. When two such objects move on each other their irregularities get interlocked and friction arises.

Question 3.
How does the nature of surface effect friction?
Answer:
Nature of the surface plays major role in production of friction. The rough surface produces more friction than the smooth surface. The rough surface has more irregularities on it than the smooth surface, so more force is required to overcome the friction caused by irregularities.

Question 4.
What is a spring balance? How does it work?
Answer:
Spring balance is a device which is used to measure the force acting on a body. It consists of a coiled spring, which is attached to pointer and scale. When some object is hung with it the spring stretches and pointer points to the graduated scale to give the measurement of the force.

Question 5.
Which friction is less static friction or sliding friction? Why?
Answer:
Sliding friction is lesser than static friction, because in sliding friction the relative motion between two surfaces is less opposed by friction as the irregularities of the two surfaces in contact do not get enough time to interlock with each other which makes the motion easy.

Question 6.
What would happen, if the floor we walk on, does not produce any friction?
Answer:
If there is no friction on the floor, we would not be able to stand or walk on the floor, because it is the friction which unables us to stand or walk on the surface. The grooves of our feet or shoes get locked into the irregularities of the floor and makes us stand. If friction is not there, then we would simply slip on the floor.

Question 7.
What helps us write with a pen or pencil?
Answer:
It is the friction between the hand and pen or pencil which causes us write with pen. The grooves on our fingers make a grip on the pen’s irregularities and we are able to write.

Question 8.
Why is it difficult to move an object from its static position?
Answer:
When an object is in its static position, it has better hold of the surface on which it is placed. The irregularities of the surface are interlocked properly and more force is needed to overcome the friction offered by interlocking surfaces. So it is difficult to move the object from its position of rest.

Question 9.
Why do we rub our hands in winter when we feel cold?
Answer:
We rub our hands to make them warm, when we feel cold. Rubbing hands against each other cause friction between them. Friction produces heat, this heat makes us warm. We can feel the warmth by touching our hands on our face.

Question 10.
Why do we need to decrease friction?
Answer:
Friction is an evil which causes a lot of wear and tear in objects coming under its effects. It causes a lot of wear in machine parts which rub against each other, it erodes the surfaces and destroy their symmetries. So, we lubricate surfaces to decrease the friction.

Question 11.
How can we increase friction?
Answer:
We need to increase friction of surfaces to control the movement. Friction can be increased by increasing the irregularities of the surfaces in contact. We use spikes in the shoes of the athletes so that they can lock better in the irregularities of the ground to make better grip.

Question 12.
How can we decrease friction?
Answer:
Friction can be decreased by rolling, sliding and lubricating the surfaces in contact. We use ball bearings, wheels and lubricants like oils, grease, cream etc. to decrease the friction. Rolling, sliding and lubricating decrease the irregularities of the surfaces and make them smooth.

Question 13.
What is drag?
Answer:
Drag is the frictional force exerted by fluids. Liquids and gases are collectively called fluids. So the friction caused due to movement of objects in liquids and in air medium is called a drag.

Long Answer Type Questions

Question 1.
What is friction? How do friction arise? Explain.
Answer:
Equal and opposite force exerted by relative motion between two surfaces is called friction. Friction is always exerted in opposite direction to the force exerted. Friction acts between two surfaces. It is caused due to the movement of these two surfaces in contact. Every surface has some irregularities on it. When two surfaces come in contact, these irregularities get locked with each other. When objects are moved, the friction arises in the opposite direction of the movement.

Question 2.
What factors effect the force of friction? Explain.
Answer:
Force of friction depends upon the nature of the surfaces in contact and the force with which these two surfaces are pressed against each other. Nature of the surface on which an object moves, effects the force of friction. Rough surfaces produce more friction, while smooth surfaces produce less friction. Rough surfaces have more irregularities on them so they produce more friction. Smooth surfaces allow easy movement as they have less irregularities and the interlocking of irregularities with other surface is less as compared to the rough surfaces, so they produce less friction.

Secondly, force of friction depends upon how hardly two surfaces are pressed against each other. If two surfaces are pressed hard against each other, then the friction produced will be more.

Question 3.
How many types of frictions do you know about? Explain.
Answer:
Friction is of different types : Static friction, sliding friction and rolling friction.
Static friction is one which is produced between two surfaces in contact with each at the position of rest. This friction is more powerful than others. It is most difficult to overcome the static friction at this positions, the irregularities are most effectively pressed against each other. This type of friction needs a lot of energy to overcome.

Sliding friction: arises when two objects in contact are in motion. It is lesser than static friction. This friction is lesser because the irregularities of both surfaces do not get enough time to get locked with each other as an object is already in motion.

Rolling friction: comes in effect when two bodies are rolling on each other. Rolling movement of both objects don’t allow the locking of irregularities, thus it is the smallest friction of all they three types. Drag is the frictional force which is exerted by the fluids on the bodies moving in it. This friction needs a lot of energy to overcome so, bodies of such objects which move in fluids are streamlined to counter the friction offered by fluids.

Question 4.
What is fluid friction and on what factors does fluid friction depend?
Answer:
Friction exerted by fluids is called fluid friction. Bodies moving in air and liquids bear friction caused by air and liquid. Air and liquids are collectively called fluids. Fluid friction is also called Drag.Drag depends upon the speed of the object with respect to fluid, nature of the fluid and the shape of the object. Slow moving objects face more friction and heavy fluids offer more friction. Objects with pointed front, face less friction. All objects moving in fluids have streamlined shape so as to minimise the friction exerted by fluids.

Streamlined objects have narrow front, broader middle portion and which tapers at the back. All living organisms moving in air and water have streamlined shapes. Birds, fish etc. have streamlined body. So, Aeroplanes, boats, ships etc are designed according to birds and fish, so that they have to face less friction and has to spend less energy to overcome the friction.

Question 5.
prove with the help of an experiment that smoothness of surface reduces friction.
Answer:
Take a pencil or pen. Now put it on a table. Slightly push the pencil and see how much distance it covers, mark the point where the pencil stops after covering the distance. Now take some.cream or oil. Make a small coating of oil on the table or spread polythene on the table if possible. Now again take the pencil and put it at the same initial point. Now push the pencil slightly and let it stop on its own as done earlier. Now mark the point where the pencil stops. See the difference in the distance. In second attempt the pencil has covered more distance. This means it had to face less friction in second attempt. It proves that smoothness of the surface reduces friction.

Question 6.
Why and how do we increase friction?
Answer:
We increase friction deliberately to control the movements and motion of the objects. We also increase the friction for better grip and hold. Friction can be increased by making surfaces coarse and pressing two surfaces harder. Coarse surface has more irregularities to grip irregularities of other surface better, thus making the things come to a halt and give a better grip if object is stationary. We use brake pads in vehicles. When brake pads are pressed by pressing the lever, it gets pressed against the tyres and arrest the movement of the tyres and with this the vehicle comes to stop.

Pens are provided with ridges at the point where we hold them for writing, so that the friction between fingers and pen becomes more and a better grip can be made to write fluently. Pens without ridges get slipped out from our hands easily.

Question 7.
Why and how do we decrease friction?
Answer:
We decrease friction to save the objects from wear and tear. Friction causes wear and tear on the surfaces of the objects. It causes damage to the objects specially machines and machine parts. So, we apply a film of oil or grease between the surfaces in contact, so that it produces less friction and it causes no damage to the parts. Oils, grease etc. are called lubricants, which are used to make surfaces smooth and minimise friction. In most of the cases rolling of objects is used to reduce friction. Ball bearings are used in cycles, vehicles and machines because it reduces friction. Wheels are used to move heavy objects because wheels roll on the ground thus reducing friction and this makes the dragging of heavy objects easy. Tyres carry heavy and loaded trucks on them, as they produce less friction and need lesser energy to move them.

Friction Class 8 HBSE Notes

1. Friction is the force equal and opposite to the relative motion between two surfaces in contact.

2. Force of friction acts on both the surfaces in contact.

3. There are many factors which affect friction :

• It depends on the nature of surface.
• It depends on smoothness of surface.
• It depends on the hardness with which two surfaces in contact are pressed against each other.

4. Friction has no relation with area exposed to force of friction.

5. Friction is static, when it opposes the force applied on the body.

6. When two surfaces slide on each other, sliding friction comes into play.

7. Sliding friction is less than the static friction.

8. Friction is an evil which causes a lot of wear and tear on the surfaces of the objects due to opposite forces in action.

9. Wear and tear is more in case of static friction and less in case of sliding friction.

10. Friction is an evil but a necessary evil. No body would have been able to walk on the floor, if friction was not in play :

11. When two surfaces roll on each other the rolling friction is applied, for example in case of wheels under attache-cases. Rolling reduces the friction and movement becomes easy and smooth.

12. Fluids also exert force of friction and reduce the speed. To avoid friction due to fluid, bodies of objects moving in fluids have pointed and streamlined fronts and bodies.

13. Aeroplanes and ships etc. have streamlined bodies to over come the friction caused by air and liquids.

(a) Kharif Crop
(b) Rabi Crop
Answer:
(a) Paddy and maize
(b) Wheat and gram

Question 4.
Write a paragraph in your own words on each of’the following:
(a) Preparation of soil (b) Sowing (c) Weeding (d) Threshing.
Answer:
(a) Preparation of Soil:
Soil is prepared to sow the seeds. It is tilled to loosen the soil particles for better absorption of water and manures. Loosening of soil particles add humus and nutrition to the soil for better crops. Tilling of soil is done by using ploughs which are pulled by bulls. Tractor driven cultivators are also used to till the soil.

(b) Sowing:
Sowing means implanting the seeds in the prepared soil. Seeds are first selected. Better and healthy breeds of seeds are selected. They are then sowed in the fields with the help of seed drills and funnel shaped tools. The funnel, has a long body on one end of which is placed in soil. Seeds are put in the funnel and seeds go into the soil through long pipe which is carried over in the field with help of ploughs, the lower end pierces through the soil, spreading the seeds. Some seeds are simply spread through the field by hand. Some saplings are planted directly in the field manually.

(c) Weeding:
Unwanted plants growing along the crop are called the weeds. These weeds absorb the nutrients from the soil which are ment for the crops. They are, therefore, removed from the fields. Weeds are either removed manually or by mechanical tools. Certain chemicals are also used to kill the unwanted plants growing in the crops.

(d) Threshing:
Separation of grains from the chaff is called threshing. Seeds are removed from the chaff by threshers. When the crop is harvested, it is cut alongwith the stalks. They are then separated and the grains are removed. This whole process takes place with the help of a huge machine called combine.

Question 5.
Explain how fertilisers are different from manure.
Answer:
Differences between fertilizers and manure:
(i) Fertilisers are chemical substances, while the manures are the organic substances.
(ii) Fertilisers are prepared in the factories while the manures are prepared in fields.
(iii) Fertilisers don’t provide any humus to soil while manures provide a lot of humus.
(iv) Fertilisers are rich in plant nutrients will manures are less rich in plant nutrients.

Question 6.
What is irrigation? Describe two methods of irrigation which conserve water.
Answer:
Watering the crops in the fields is called irrigation. Irrigation is done at different intervals. Irrigation should be done in a way in which water does not get wasted, two such methods which conserve water are:
(i) Sprinklers:
Sprinklers work like fountains. Long perpendicular pipes have holes at regular distances, when water is supplied, it comes out of these holes and spray water in field. These holes have rotating nozzles which sprinkle water in all directions. Limited outflow of water, controls wastage of water.

(ii) Drip System:
This system allows the water to flow drop by drop at the roots of the plants. It contains a main pipe which have further lateral pipes containing small nozzles for the outflow of the water. Nozzles are such placed that they throw water at the roots of the plants, which saves water from flowing around uselessly.

Question 7.
If wheat is sown in kharif season, what would happen? Discuss.
Answer:
If wheat are grown in Kharif season, they would not grow as they do not need ihuch water to grow. The seeds would get destroyed in excess water due to rainy season.

Question 8.
Explain how soil get affected by the continuous plantation of crops in a field.
Answer:
Continuous plantation of crops drains off the nutrients of the soil. It leaves the land unfertile and unable to bear crop. It does not give any time to the soil to replenish the absorbed nutrients by the crops, thus unable to sustain any further healthy and good crop.

Question 9.
What are weeds V How can we control them?
Answer:
Weeds are the unwanted plants growing along crops. They share the nutrients meant for plants and thus are harmful. We can control weeds with the help of chemicals called weedicides. Weeds are the unwanted plants growing along the main crops. They are either removed manually or by chemicals. Weedicides are sprayed in the fields to kill the unwanted plants. These weedicides do not affect the main crop. Weeds are removed or killed during their vegetative phase before flowering or bearing seeds.

Different methods of irrigation are adopted according to the requirement of soil and size of the field. Some common methods of water supply are through small channels, which get water from tubewells and canals, lift irrigation, sprinkler, dripping irrigation, etc.

Question 8.
Define weeding. What tools are used for weeding?
Answer:
Weeds are unwanted and undesirable plants which grow alongwith the crop plants in the field. They grow rapidly than the crop plants and cause harm to them. It is, therefore, essential to remove weeds at proper time. The process of removing the weed plants is called weeding. It is done either by hand or by khurpi. It is also done by spraying chemicals or weedicides.

Question 9.
What is humus? How is it formed?
Answer:
Humus is a kind of soil rich in nutrients. It is formed by the microbial action on dead decaying bodies and leaves. It is generally formed on those spots where-there are dense layers of trees. The soil below it becomes dark having more number of pathogenic bacteria.

Question 10.
What are pesticides?
Answer:
The chemicals which are used to protect crops from the organisms called pests are known as pesticides. They are used to kill eggs and larvae of insects who could cause harm to the crops. Pesticides are sprayed in the fields by different methods at different intervals.

Question 11.
What safety measures are to be taken in handling pesticides and weedicides?
Answer:
Insecticides and pesticides are highly poisonous chemicals. They kill the pests. They can harm the humans also. So, certain precautionary measures should be taken while spraying pesticides and weedicides.

They should be kept away from the reach of children.
They should not be inhaled while spraying. Gloves and mouth covers should be used while spraying them.
Hands should be washed properly after their use.

Question 12.
Distinguish between pesticides and weedicides?
Answer:
Weeds are controlled by using certain chemicals called weedicides. These chemicals do not cause any damage to the crop.
Pesticides are the chemicals which are used to kill the pests growing on the crops. They kill the eggs and larvae of the insects.

Question 13.
Explain the process of harvesting?
Answer:
The removal of crop after maturity is called harvesting. The harvesting is done manually with the help of ordinary sickles in crops like wheat, paddy and maize. Even tractor driven machines are also used for harvesting wheat and paddy. Fruits and vegetables are plucked manually.

Question 14.
Explain the process of threshing,
Answer:
The crops need to be threshed to separate grains from the chaff. The mechanical harvesters help in both threshing and separating the grains. The small farmers thresh their crops by spreading the crops on the ground and walking of animals over it. Now-a-days threshing is done by threshing machines driven by tractors or electric motors, which separate grain from chaffs.

Question 15.
What factors influence the crop production?
Answer:
The factors that influence the crop production are as follow:
(i) “Soil: It is the upper layer of earth’s crust. It is the natural medium which supports plant growth.
(ii) Water: Plants require water during various stages of their growth and development such as germination, flowering, ripening, etc.
(iii) Air: Air is essential for breathing and photosynthesis.
(iv) Sunlight: It is essential for plants as a major promotion factor for photosynthesis, germination and flowering.

Question 16.
Suggest ways for the improvement of crops.
Answer:
Following ways should be adopted to improve the crops:
(i) Use of improved seeds.
(ii) Improve fertility of soil.
(iii) Protection against pests and weeds.
(iv) Better transport and storage facility.
(v) Introduction of high yielding varieties of seeds.

Long Answer Type Questions

Question 1.
What are some basic principles of crop production?
Answer:
There are certain conditions which are very important for causing the good crop yield. Good and right kind of soil, seeds, water and protection of crops from weeds and pests as well as the use of proper implements and practices- all go to determine the quality and reliability of crop yield.

A field or farm needs to be managed properly in order to get better yield. Farmers, therefore, must observe some important things which are listed below:
(i) The crop field should be open so that sunlight and air are abundantly available.
(ii) The field should be protected from stray cattle and tresspass which may destroy the crop.
(iii) The soil should be loosened and turned before sowing so that the plant roots can penetrate into it easily and are well ventilated. The latter helps in holding the plant firmly. Root and tuber crop plants need loosened soil for proper growth of the plant product.
(iv) The right amount of water should be available neither too less nor too in excess.
(v) The soil should contain sufficient nutrients for the growth of the plants.
(vi) The unwanted plants such as weeds should be removed from the soil. These weeds compete with the main plants and deprive them of their nourishment.

Question 2.
What is the use of soil for the plants?
Answer:
Soil plays an important role in agriculture in following ways:
(i) Soil fix up the plant in the soil. It holds the roots firmly and anchor the plant.
(ii) Soil has the power of retaining the water which helps the absorption by plants. It also contains minerals etc. which provides food nutrients to the plants.
(iii) It also provides space for living to useful animals such as earthworms which turn up soil and make it fertile.
(iv) Soil holds air in its gaps. This air is used by the plant for its respiration as well as for the respiration of the useful plants and bactria.

Question 3.
How are pests controlled in a crop field?
Answer:
Pests are the organisms smaller bugs which damage the crop plants in the field, during transportation, in the godowns. The common pests are birds, rats and other rodents, some animals, insects and micro-organisms belonging to different groups. They are harmful as they destroy the crop. Pests like locusts, beetles, red spiders, aphids, etc. can be controlled by three methods.
(i) Chemical control: The use of pesticides like DDT, malathion, BHC and aldrin. These chemicals are quick and effective way of controlling the growth of the pests.
(ii) Biological control: One insect feeds von other insect. In this method harmless insects are introduced in the field which will be harmful for insects and other pests.
(iii) Growing pests resistant varieties: Breeding crop varieties which are resistant to pests is a very effective and common method of pest control.

Question 4.
Why do we irrigate our crops? Explain.
Answer:
Water is required by the plants for the following activities:
(i) The seeds sown in the soil absorb water for various activities related to germination, such as activation of phenul, radicle and embryonal axis.
(ii) Water is essential for softening of soil particles so that the roots may penetrate deeply into the soil easily.
(iii) The mineral salts, manure particles, etc. dissolve in water and make the dilute solution. It is easily absorbed by the root hair.
(iv) Water is essential to maintain the turgidity of the cells and to keep them inactive form.
(v) Water is evaporated from the soil as well as from the aerial parts of the plants. Irrigation is essential to fill up the loss of water.
(vi) For the preparation of food by the plants through the process of photosynthesis, water is very essential.

Question 5.
Why an earthworm is called a friend of a farmer?
Answer:
Before sowing seeds every farmer prepares his soil for sowing. He digs the soil. He does tilling with help of tractors and ploughs. This all is done to loosen the soil particles so that air .and nutrients can be easily absorbed. Earthworm is an organism which lives under the soil and make burrows for itself. This burrowing action loosens the soil for better penetration of roots of the crops.

It create channels through the field which improves the physical properties of the soil. The burrowing action of earthworm improves soil structure, helps in formation of humus mix and till the soil and increase the supply of nutrients of the plants.

Question 6.
Write a short note of thresting and winnowing.
Answer:
When a farmer cut his crops, he has to separate the grains from the crop it is done in two ways. Manually and with machines.

The separation of seed from the crops by beating out the seeds (grain) from the crop is called threshing. It is done manually or by using threshers with combines.

After separating the grain from the harvested crop, it is required to separate grain from chaff. This process is done by winnowing. The grains are thrown from the height in the direction of air. The air carries away the lighter chaff or dried stems and leaves and the heavier grains drop down in form of a heap. This whole process is called winnowing.

Crop Production and Management Class 8 HBSE Notes

1. All living beings need food to live and perform various other activity.
2. We get food from plants and animals. The plant food is grown in fields making use of various processes. This is called agriculture.
3. All plants of same types grown together are called crops. Different types of crops are grown in the fields e.g. cereals (wheat, paddy rices) fruits and vegetables, etc.
4. Based on seasons many crops are grown. Rainy season crops are called Kharif. Winter crops are called Rabi and Summer crops are called Zayed crops.
5. To grow a crop a number of activities has to be performed. These are called agricultural practices. These agricultural practices include: soil preparation, sowing, adding manure and fertilizers, irrigation, protection from weeds, harvesting, storage, etc.
6. Preparation of soil includes loosening soil. This is called tilling or ploughing. Plough, cultivator and hoe are used as tools.
7. Sowing means putting the seeds in the loosened ground to grow.
8. For a healthy and good crop manure and fertilizers are added to the crop. These are chemicals which enhance the crop production.
9. When we grow crop in the field it takes all the nutrition away from the soil. This nutrition is – required for the next crop. The soil is replenished with nutrition by these fertilizers and manures. Crop-rotation is another method of replenishing nutrition in soil.
10. Crops are watered sufficiently by canals, drips and rainwater. This is called irrigation of crops. Irrigation is the most important process of crop production.
11. Undesirable plants growing among the crops are removed manually or by machines. These unwanted plants are called weeds, chemicals used to kill weeds are Called weedicides.
12. Sometimes some small animals start eating the crops. These are called pests. Special chemicals
are sprayed on the crops to kill the pests. These chemicals are called pesticides.
13. After the crops are ready, they are harvested. Grains are separated from the chaff. This process is called threshing. Threshers are used to do this process.
14. The harvested grains are then Stored in huge stores, after they are properly dried in sun. These stores kre called granaries.
15. We also get our food from animals. For this purpose some useful animals are domesticated
and reared. This is called Animal Husbandry. Animals like cows, buffaloes, goats, hens etc. are domesticated for food.

HBSE 8th Class Science Reproduction in Animals Textbook Questions and Answers

Question 1.
Explain the importance of reproduction in organisms.
Answer:
Reproduction is very important for the organisms. The organisms reproduce to produce young ones like them. It carries on their generation. If reproduction does not take place, no living being would survive on earth. Secondly, specials characters of an organism are carried over to its next generation through reproduction only.

Question 2.
Describe the process of fertilization in human beings,
Answer:
Human beings reproduce sexually. In human beings fertilization takes place internally i.e. inside female body. Males eject sperms inside females body. Sperms and ovum fuse to form the fertilized egg called zygote. During this process the nucleus of the sperm fuses with the nucleus of the ovum thus forming a single nucleus.
Thus zygote is formed with a single nucleus, this completes the process of fertilization.

(f) False
(g) False
(h) True
(i) True
(j) False.

Question 5.
Give two differences between a zygote and a foetus?
Answer:
(i) Zygote is made up of a single cell while foetus is made up of many cells.
(ii) Zygote does not have well developed limbs, foetus has well developed and identifiable limbs.
(iii) Zygote is formed by the fertilization of sperms and ovum, foetus is formed by the repeated divisions of the zygote .

Question 6.
Define asexual reproduction. Describe the two methods of asexual reproduction in animals.
Answer:
Asexual reproduction is that type of reproduction in which only single parent is involved. Asexual reproduction takes place by different methods like budding, binary fission etc. Let us discuss these two methods:
(i) Budding:
This type of reproduction takes place in Hydra and Bacteria. A part of the organism starts bulging out. Slowly it grows and develops into a separate individual.

(ii) Binary fission:
In this type of reproduction, a single organism gets divided into two. This type of reproduction takes place in Amoeba. The nucleus of the Amoeba gets divided into two followed by division of their bodies, each part getting one nucleus and developing into separate individual.

Question 7.
In which female reproductive organ does the embryo get embedded?
Answer:
Uterus.

Question 8.
What is metamorphosis? Give examples.
Answer:
Drastic changes which take place during the development of an animal is called metamorphosis. Animals like frog, butterfly undergo metamorphosis.

Question 9.
Differentiate between internal fertilisation and external fertilisation.
Answer:
Internal fertilisation takes place inside the body of the female while the external fertilisation takes place outside the body of the female.
In case of internal fertilisation sperms are ejaculated in female’s body by the male. In external fertilisation sperms are discharged in I open.

Question 10.
Complete the cross-word puzzle using the hints given below.

Short Answer Type Questions

Question 1.
What is reproduction? Why is it important?
Answer:
Reproduction is giving birth to organisms of same kind. Reproduction is important to continue life on earth and to maintain different special characters of different species.

Question 2.
What are different modes of reproduction?
Answer:
Reproduction takes place by two methods. In one method a single parent is involved in the process of reproduction. This is called asexual reproduction. In second method both male and female i.e. both parents are involved in the process of reproduction. This kind of reproduction is called sexual reproduction.

Question 3.
What are the names of male reproductory organs in human beings?
Answer:
In human beings male reproductory organs are a pair of testes, sperm ducts and a penis. Testes are responsible for producing male gametes called sperms. They are transported to the sperm ducts and through the penis, they are ejaculated in female body.

Question 4.
Explain the reproductory organs of female in human beings.
Answer:
In human beings the female reproductoiy organs are a pair of ovaries, oviducts or fallopian tubes and the uterus. Ovaries are responsible to produce female gamete called ova, which fertilize with male sperm in female fallopian tube and travels to uterus for its development into embryo and the foetus.

Question 5.
Describe the human male and female gametes.
Answer:
In human beings the males produce the gamete called sperms. Sperms are very small in size. They have a head with a middle piece which end into a tail. It is a single cell. Similarly, female gamete ova is produced by ovaries. Every ova is a single cell and one matured ova is released by one ovary every month.

Question 6.
What is fertilisation?
Answer:
When a male and a female gamete come in contact with each other they fuse. The male sperm enters the female ova and the nucleus of the sperm fuses with nucleus of the ova and results into a single nucleus. This whole process is called fertilization. In short fertilisation is the fusion of male and female gametes.

Question 7.
Explain how external fertilization takes place?
Answer:
In this case the females lay eggs in slow moving streams. The males also release sperms on this cluster of eggs. The sperms move in water with the help of tail and when come in contact with egg, they get fertilized.

Question 8.
How is an embryo formed put of a zygote?
Answer:
Zygote is a single cell formed by the fusion of male and female gametes. It undergoes repeated numbers of division to form a lot of many cells, so that the limbs and other parts can be developed. Thus a single zygote gets divided to form an embryo.

Question 9.
How is an embryo formed in case of hens?
Answer:
In hens zygote divides many times and reaches the oviduct. During this a protective outer coating is formed around the embryo. The complete embryo develops inside this protective shell. This embryo is laid by the hen along with the shell as an egg. This egg finally hatches after ‘ three weeks to produce chick.

Question 10.
What is budding?
Answer:
Budding is an asexual method of reproduction in animals. It needs only a single parent to reproduce. The body of the animal starts developing a small bulging structure called bud which slowly grows and have itself disconnected from the parent animal and becomes a separate individual. This is called budding. Animals like hydra reproduce through budding.

Question 11.
What do you mean by binary fission?
Answer:
Binary fission is a method of asexual reproduction. In this method the body of the animal divides into two halves. The nucleus of the body divides into two and this is followed by the division of the whole body. So, two organisms get produced with separate nuclei. Animals like Amoeba reproduce by this method.

Question 12.
What is cloning?
Answer:
Cloning is a method of producing an identical organism, a body part or only a cell. The produced organism or cell is completely identical to its original organism or cell. This method has been used many times in animals to produce identical clones.

Long Answer Type Questions

Question 1.
What do you mean by reproduction? Write about different modes of reproduction.
Answer:
Reproduction is the process of producing young ones of the same kind. Reproduction is a very important process. It is the only means of keeping the life on the earth.
There are two modes of reproduction:
(i) Sexual Reproduction:
Reproduction process in which a male and a female parents are involved is called sexual reproduction. In this process both parents produce gametes which fertilize to produce a zygote, which further develops into a baby. Human beings, cows, dogs etc. reproduce sexually.

(ii) Asexual Reproduction:
When a single parent is responsible for producing a young one, it is called asexual reproduction. Budding, fragmentation, spore formation Binary fission etc. are different methods of asexual reproduction. Microorganisms like Hydra, Amoeba, bacteria etc. reproduce asexually.

Question 2.
Draw and describe the male reproductive organs in humans.
Answer:
Male reproductive organs consist of a pair of testes, sperm ducts and penis. Testes are responsible for producing male gamete called sperm. Sperm is very small in size. It has a head, a middle piece and a tail. Sperms travel through sperm ducts and penis, and are released in female body for fertilization.

Question 3.
Draw and explain the Female Reproductive organs in human.
Answer:
Female reproductive organs consist of a pair of ovaries, oviduct or fallopian tubes and uterus.

Ovaries produce the female gamete called Ova. Every month an ovary produces an ovum. The ovum and sperm fertilize inside fallopian tubes and the fertilized zygote travels to the uterus and attach with its wall to develop into the foetus.

Question 4.
What is fertilization? How does it take place?
Answer:
Fertilization is the process by which the male and female gametes fuse to form the zygote. The sperms from a male are transferred into the female body. They swim to the fallopian tubes with help of their tails and one of them enters the ovum to fertilize. When the sperm enters the ovum, the nucleus of both the gametes fuse with each other to form the fertilized zygote.

The fertilized egg is called zygote. This zygote develops into foetus by repeated cell division. When the fertilization takes in the body of female, it is called internal fertilization. But many animals release their gametes into water and fertilization takes place outside the body of female, then the fertilization is called the external fertilization.

Question 5.
What is asexusal reproduction? Describe different methods of asexual reproduction.
Answer:
The reproduction in which only a single parent is involved is called asexual reproduction. This type of reproduction takes place mostly in microoganisms. Following are the methods of asexual reproduction:
(i) Budding:
This type of reproduction takes place in Hydra. The body of the hydra starts developing small bulges. These bulges are called buds. These buds grow in size and finally get detached from its body and become a separate individual.

(ii) Binary Fission:
This type of reproduction takes place in Amoeba. The body of the organism divides into two. The nucleus of the organism divides into two and then the body of Amoeba divides, each part getting each nucleus and thus becoming two separate individuals.

Reproduction in Animals Class 8 HBSE Notes

1. Each living being reproduce to give birth to young ones exactly like them.
2. The process by which young ones are produced is called reproduction.
3. Reproduction is of two types: Sexual reproduction and asexual reproduction.
4. When a male and a female gamete fuse to give birth to a young ones, then it is called sexual reproduction.

6. Reproductive organs in males and females are different. In females the reproductive organs are ovaries oviducts and uterus. In males the reproductive organs are a pair of testes, sperm ducts and penis.
7. Ovaries produce female gamete called ovum and male gamete called sperms are produced by testes.
8. Ovum and sperm fuse to form egg called Zygote. The process of fusion of ovum and sperm is called fertilization.
9. Fertilization is of two types: When it takes place inside the females body, then it is called internal fertilization, but when ovum and sperms fuse out side the body, it is called external fertilization.
10. Embryo is formed from the zygote by repeated divisions, which grows in the uterus of the female in case of internal fertilization. Embryo grows into foetus when it gets well developed limbs.
11. When animals give birth to a young one it is called a viviparous animals e.g. man, cow etc. When animals lay eggs, they are called oviparous animals e.g. hen, butterfly, etc.
12. In asexual reproduction organisms reproduce by budding binary fission, fragmentation etc.

Do you think the victims can get justice if only one person performed all the functions of the criminal justice system? Why not?
Answer:
The victims cannot get justice if one person performed all of the functions of the criminal justice system. Every function requires special skill to perform the task and also if one person performs all the functions, there is least possibility of cross-check. The police receives a complaint, the defence lawyer tries to defind the accused, the judge gives decision in the court and decides the punishment for the culprit. If only one person performed all the functions of the criminal justice system, that will lead to end of democracy.

State two reasons why do you believe that different persons need to play different roles as part of the criminal justice system.
Answer:
The two reasons to support the view that different persons need to play different roles as part of the criminal justice system are:
(i) The police and the judges are on one side and the Public Prosecutor and the Defence Lawyers on the other. This keeps a balance between two sides of the judicial edifice and ensures an impartial and fair justice.

(ii) If the duty of charging a person and punishing him is given to a single person, it would be the end of a democracy. In such a situation, the Fundamental Rights will have no meaning.

Why do Adivasi activists including C.K. Janu believe that Adivasis can also use this 1989 Act to fight against dispossession? Is there anything specific in the provisions of the Act that allows her to believe this?
Answer:
Being an Adivasi Activist, C.K. Janu is right in believing that they can use the 1989 Act to fight against dispossession. This is because it lists actions that dispossess Dalits and Adivasis of their meagre resources or which force them into performing labour of slavery.
Thus, they can use this Act since it seems to punish anyone who wrongfully occupies or cultivates any land owned by, or alloted to, a member of a scheduled caste or a scheduled tribe or gets the land alloted to him transferred.

Answer:

(c) For example:
A poem by Soyrabai: (Refer Pg. 96 of your Social Science and Political Life-III text book). (Read the poem and then the summarised view below.)

Soyrabai who herself belongs to the Mahar caste through her esteemed poem questions about the idea or the criterion behind being called a pure person. She argues that every human being is born in the same way and is equal. She cannot understand what makes one body less or more pure than the other. Pollution, a basic idea of casteism should not be the tool for discrimination or to separate or deny people any access to spaces, work, knowledge or dignity. According to her, it does not occur through nature of work but through one’s clear ethnicity and beliefs.

In India, we have an integrated judicial system. What does it mean?
Answer:
It means that the decisions made by higher courts are binding on the lower courts. This integration can also be understood through the appellate system that exists in India. It means that a person can appeal to a higher court if he believes that the judgement passed by the lower court is not just.

Answer:
In our courty the courts are available for all. But in reality, access to courts has always been difficult for a vast majority of the poor in India.

Therefore, the Supreme Court devised a mechanism of Public Interest Litigation.

Rani Lakshnjibai of Jhansi : The Raja of Jhansi had been originally a vassal of the Peshwa. After the defeat of Baji Rao II, Lord Hastings in 1818 had concluded a treaty with the Raja on terms of‘subordinate co-operation’.

After the death of the Raja in 1835, the company recognised a grand-uncle, Raghunath Rao to succeed to the throne. After his death, his successor Gangadhar Rao was recognised as the ruler in 1838. But he died in November 1853 without leaving a male heir and the state was declared annexed by Lord Dalhousie. The claims of the adopted son were disregarded. So the Queen of Jhansi Rani Lakshmibai joined to revolt to protest against the annexation of Jhansi by the English.

When the Rani joined the revolt, General Sir Huge Rose attacked Jhansi in March 1858, but the brave Rani Lakshmibai kept the British General unnerved for quite sometime.

But by the time he reached Jhansi her troops were severely defeated by the British on the banks of the river Betwa. Now the Rani had to hold on to her fortress above. The British also knew it would be difficult for them to enter into the fortress.

So the British resorted to deceit and treachery and bribed the guards to open the gates of the fortress. Even then the British was unable to capture the Rani who slipped out of the fort and reached Kalpi. Here she was joined by Tantya Tope the great general of Nana Sahib, who fled to Kalpi. Now the Rani of Jhansi and the great General Tantya Tope joined together and fought many wars with the British. While fighting they had to leave Kalpi. So they fell upon Gwalior with lightening speed and captured it. The ruler of Gwalior Jayaji Rao Sindhia was a dependent ruler of the British Company who was paying lots of tribute and he was also very loyal to the Company. Now the Company had the responsibility to protect their independent, i.e., the ruler of Gwalior.

A fierce battle was fought between the British and the revolutionaries under Rani Lakshmibai and Tantya Tope from June 11-18, 1858 A.D. Even though the Rani and Tantya Tope were able Generals, their personal valour was not at all a good match the resources at the command of the British. Gwalior was recaptured by the British in June 18,1858. The Rani of Jhansi died fighting clad in soldier’s uniform on the ramparts of the fort. Tantya Tope escaped southward. In April 1859 he was captured by one of the Sindhia’s feudatory, who handed him over to the British to be hanged on April 18, 1859.

Sir Huge Rose paid a tribute to the valour of Rani Lakshmibai by saying, “Lakshmibai was the bravest and the best of military leaders of the rebels.”

LETS IMAGINE

Imagine you are a British officer in Awadh during the rebellion. What would you do to keep your plans of fighting the rebels a top secret?
Answer:
I would have used a code word Kamal (Lotus) to convey about my future plans. I knew that Kamal was being used by the rebellion, just to create confusion in the minds of the Indians.

I used to wear Indian dress of the area. I would keep a large number of troops, judging their loyalty. I would have asked the Muslim soldiers to take an oath of Holy Quran of loyalty to the British and same oath by the Hindu soldiers, telling them to put their hands on Holy Bhagwat Gita.

I would have used all four tactics of Sam, Dam, Dand and Bhed to loyalty among the rebels of the Awadh. I would have send some loyal females to know future plan of the higher British officers.
