Question

seeds are light then why can't seeds of all plants be dispersed by wind? why are they dispersed in different ways

Answer 1

imagine that you have a mango seed and a dandelions seed on your hands. checking its weight. you will find that mango seed obviously weighs more than the dandelion seed. if you notice it closely, you will also find the dandelion seed has feathery bristles which make it easier for the wind to carry it for over a long distances. but this is not found in the mango seed. and so mango has no chances to fly in air and get dispersed! since mangoes are really tasty it is the mammals who do the work. same is the case with all the other seeds. the seeds may seem light to us but the point of view of the wind should be considered here as it is the one who does the work.

hope you find this helpful.

Hello friend!
Here's ur answer!
Seeds from plants like dandelions, and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind while the winged seeds flutter to the ground. The seeds of other plants are not feathery so they cannot be dispersed by wind. 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.
