Dispersal

Dispersal is a universal biological need, and it is to be expected that most higher plants have solved the problem in one way or another through adaptations involving their fruit or seed.

dispersal of the species to new locations (aided in angiosperms by the fruit)
survival of the species during unfavorable climatic periods (e.g., winter). "Annual" plants (e.g., beans, cereal grains, many weeds) can survive freezing only as seeds.

Dispersal (sensu ecology): the transport of propagules away from the parent. Diversity: a) the total number of species present;
b) some index which incorporates both the number of species and the relative abundance of each.

Its function is seed protection and dispersal. Fruits are a development of the ovary wall and sometimes the other flower parts as well. Its formation is induced by the plant hormone
auxin
, which is released by the maturing seeds.
