What tree uses wind dispersal?
What tree uses wind dispersal?
Seeds that use the wind to travel away from the parent plant, called wind dispersal, include helicopters and floaty seeds. Helicopters from maple trees and the cottony fluff of Cottonwood are some of the most visible seeds of this kind.
How does seed dispersal by wind?
