Question

write a note on the modes of dispersal of seeds.

Answer 1

there are many ways in which seeds can be dispersed :

by wind : when the wind blows from any direction, the seeds from the plant flies or falls down at a place and gets grown there.

by water : some of the plants and trees are nearer to some of the water bodies.when the seeds from the plants fall on the water , the water then takes the seed to different places and hence the seed grows in that place.

by animals : when some animals eat the plants and their seed, there is a chance that the seed does not get digester in their stomach . so , when the excretes of the animals are put in a place the seeds from the excretes may grow as a plant .

by humans : when we humansmove to some regions like forest and garden,the seeds may get attached to the clothes of us . by this it comes with us and falls on a particular place and hence the seed is dispersed.

Answer 2

Seed dispersal is the movement or transport of seeds away from the parent plant. Plants have very limited mobility and consequently rely upon a variety of dispersal vectors to transport their propagules, including both abiotic and biotic vectors
