How are fruit seeds dispersed?

Which fruit types are dispersed by wind?

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.

How are dry fruits dispersed?

Many dry fruits have hooks or teeth, which catch on animal fur (or clothing!) for dispersal. The small seeds above give the plant which produces them the names “beggarticks,” “tickseed,” and “stickseed.” Burdock fruits (below, color photo and SEM) inspired velcro (lower right).
