Matured and ripened ovaries. Holds and protects the seeds until they mature. Helps in the dissemination or dispersal of the seeds. Does not only apply to those that have edible portions, but also to those which are commonly referred to as vegetable.

Why is dispersal important? insects — insects much less important for dispersal than pollination, but ants often involved in dispersal Avoid competition with parent and siblings birds, mammals, reptiles, and even fish — much more important for dispersal than pollination Colonize new habitats wind — important in both pollination and dispersal Avoid pathogens and predators water — minor importance in pollination, somewhat greater Minimize inbreeding in dispersal self dispersal — just like some plants carry out self pollination, some plants have mechanisms for self dispersal. Methods of dispersal are often tied to certain habitats Wind —— prairie/grasslands,prairie/grasslands, mountains, forest trees, weedy areas External attachment to animals — forest plants relatively low to ground Ingestion by animals — forest plants Water — plants that grow in wetlands and along streams Ballistic — various; some parasitic plants, some forest plants, some weedy plants.
