Detailed explanation-1: -Wind dispersal Winged fruits are most common in trees and shrubs, such as maple, ash, elm, birch, alder, and dipterocarps (a family of about 600 species of Old World tropical trees). The one-winged propeller type, as found in maple, is called a samara.
Detailed explanation-2: -Seeds having wing are dispersed by air.As they are light in weight and have modifications for dispersal through air.
Detailed explanation-3: -Some fruits-for example, the dandelion-have hairy, weightless structures that are suited to dispersal by wind. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate.
