In many species, what is called the "seed" is an achene, a fruit containing the seed. Viviparous plants produce seeds that germinate immediately while still attached to the plant. Seed dispersal by ants is very important in Australia, with many plants relying on, and consequently encouraging, ants to disperse their seeds.

The size of the seed is not a factor in determining whether or not a seed can float. Plants living along streams and rivers have seeds that float downstream, and therefore germinate at new sites. Methods of Dispersal of Fruits and Seeds: Dispersal by Wind: Either the whole fruit or the individual seeds may be suited to dispersal by wind. Wind dispersed seeds and fruits have a variety of adaptations which help them to be carried away by wind. Sow seed in a trench during mid- to late summer. Gravity causes fruits to fall from the plant when ripe. A dispersal vector is an agent of biological dispersal that moves a dispersal unit, or organism, away from its birth population to another location or population in which the individual will reproduce. Method # I. Dispersal by Wind: For easy dispersal by wind seeds have to be light so that their buoyancy may enable them to float on air over long distances.
