1. I find relationship between the weight of the seeds and the dispersal mechanism.
2. 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.
3. Another example: coconut fruit
4.
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.
5. 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.
6. Similarly animals, Human beings carry the seeds to other places.
