Various ways by which seeds are dispersed are:
(i) Dispersal by wind: Light seeds or hairy seeds and hairy fruit get blown off with the wind to far away places. Examples: Sunflower, maple, drumsticks etc.
(ii) Dispersal by water: Fruits or seeds which develop floating ability in the form of spongy or fibrous
outer coat are carried away with to different places. Example: Coconut.
