1. We know that seed dispersal is necessary to grow tiny plants of the same species. 

2. To avoid competition with the mother plant for air, water and minerals plants disperse their seeds to different distances. 

3. But the process of dispersal varies from plant to plant. 

4. Plants have special mechanism for seed dispersal.

1. We know that after fertilization ovary develops as fruit and ovules develop into seeds. 

2. When the seeds germinate they give birth to new plants.

1. We have observed that fruits and vegetable plants that grow in our home garden produce a large number of seeds. 

2. Some fruits grow in singly whereas some are in bunches. 

3. Some fruits have a single seed in them and some have a large numebr of seeds. 

4. All the seeds of a fruit should be able to germinate to produce new plants. 

5. Actually this does not happen. If this happens we will see only same type of plants in large number in our surroundings. 

6. All seeds don’t germinate. Some seeds never germinate to produce new plants. Some seeds germinate but plants die before maturation. 

7. To overcome these problems plants produce a large number of seeds

1. A mustard plant produces more than 10,000 seeds in its lifetime. 

2. If all the seeds germinate to grow into adult plants, think how many seeds would be produced. If this happens for a period of six years the entire globe will be covered with mustard plants.

1. Some seeds are sticky and get stuck to the beaks of birds and in course of flight they fall down at distant places. 

2. Often some birds carry seeds with their beaks. Some of them fall before they reach their nesting places. 

3. We know some seeds have to pass through the guts of some birds before they germinate. 

4. Birds like Bulbuls, Mynahs, Crows eat some fruits (Eg: Neem fruit) the outer fleshly part gets digested in the food canal and the seed coats of them become tender. 

5. They are then dispersed to other places as bird droppings.

1. Nowadays we see diffeernt kinds of fruits and vegetables around us. 

2. Import and export of grains like wheat pulses, maize, paddy is a common practice through which many seeds get dispersed all over the world. 

3. It is a wonder now that seeds also travel by aeroplanes and ships.

Correct option is C) Underground

Correct option is C) Hairy parts

1. It collects a lot of nuts and hides them underground before onset of winter. 

2. It can hardly eat all of them and even forget where it has hidden its nuts! 

3. Thus we have several nut trees at different places.

Correct option is C) Animals

Correct option is B) Bursting mechanism

1. Coconut fruit floats on water and moves from one place to another. 

2. The outer covering of the coconut seed has empty spaces filled with air and are fibrous. 

3. This is the reason for coconut fruit to float on water. 

4. When the coconut fruit reaches ground it germinates there. 

5. That’s why usually coconut trees grow along the seashores.

1. Sprouts contain many nutrients needed for human body. 

2. Sprouts do not contain harmful contents that cause damage to the health of human beings. 

3. Sprouts give not only energy but also health to human beings. 

4. These are the main reasons for people to eat sprouts now-a-days.

Yes, It is correct I support her because 

1. The seeds of a plant should be dispersed to different places for the plants of the – same species to be grown there. 

2. As a result of this dispersal, there will not be competition for space, air and other nutrients between the mother plant and daughter plants. 

3. Plants Of any species will not be populated at one particular place but will be distributed to different places.

1. Soap nuts will be transported to different places by any means. 

2. During the transport, the seed must be intact without any damage. 

3. Some birds may swallow it and come out as a dropping on the way of their flight. It is in a very hard shell, the seed is not damaged.

Ovules develop into seeds.

After fertilization ovary develops as fruit.

Correct option is B) Caltropis

Correct option is D) Ladies’ finger

Correct option is A) Mustard
