DENDROLOGY

Detailed explanation-1: -Seeds of some plants are light-weight and some hair-like or wing-like structures are present on them. Such seeds float on air and are thus dispersed by wind.

Detailed explanation-2: -For example, wings are associated with wind-dispersal, whereas fleshy structures are associated with animal dispersal. As with pollination syndromes, dispersal syndromes can be used to infer the likely dispersal mode of a particular fruit or seed type.
