Question

Describe any two ways by which seeds are dispersed.

Answer 1

Seeds are dispersed in many ways.

(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

Answer 2

There are mainly five modes of dispersion. As you ask for only 2 I'm only explaining that:

1.Wind dispersal

Seeds which are commonly lighter and has hairy structures are commonly dispersed by this method, they breeze through the wind. eg. Dandelions, maples, etc.

2.Animals

The common way of dispersion. You eat eat a mango and throw away the seed. You have just helped a tree to sustain its kind. Dispersion of this type by an animal is known as dispersion by animals.

Hope it helped you :-)
