Answers
1) Seeds dispersal is essential for the survival of plants.
- If seeds are not dispersed, there will be competition with the mother plant for air, water and minerals.
- Most of the seeds won’t germinate.
- If seed dispersal is not there, we can’t see different plants in different areas.
- If seed dispersal is not there, we can see only a few plants in our surroundings.

2) Caltropis seeds are dispersed through wind.
- Caltropis seeds have light and hairy structure at one end.
- They travel with wind and settle at a suitable place to germinate.

3) Coconut fruit floats on water and moves from one place to another.
- The outer covering of the coconut seed has empty spaces filled with air and are fibrous.
- This is the reason for coconut fruit to float on water.
- When the coconut fruit reaches ground it germinates there.
- That’s why usually coconut trees grow along the seashores.

4) I find relationship between the weight of the seeds and the dispersal mechanism.
For example: Seeds of caltropis.
- a) These are light and have hairy structure at one end.
- b) So they travel with wind and settle at a suitable place to germinate.
- c) Milkweed, cotton seeds etc., are all dispersed by wind.
Another example: coconut fruit
- a) The outer covering of the seed has empty spaces filled with air and are fibrous.
- b) The coconut fruit floats in water and reaches the ground somewhere. There it germinates.
- c) Seeds of lotus is another example.
Another example: Neejn fruit.
- a) Birds like Bulbuls, Mynahs, crows eat the outer fleshy part gets digested in the food canal and the seed coats of them become tender.
- b) They are then dispersed to other places as bird droppings.
- Similarly animals, Human beings carry the seeds to other places.

5) Yes, It is correct I support her because
- The seeds of a plant should be dispersed to different places for the plants of the – same species to be grown there.
- As a result of this dispersal, there will not be competition for space, air and other nutrients between the mother plant and daughter plants.
- Plants Of any species will not be populated at one particular place but will be distributed to different places.
