Water Dispersal Hydrochory The seed in this type of dispersal contains tissue for the seed to be buoyant. Sometimes the seed itself will not float, but the fruit that the seed is enclosed in will.

Animal Dispersal Zoochory Divided into three groups: Endozoochory – seeds are eaten and pass through the digestive tract Epizoochory – seeds become attached to animal and become detached later Synzoochory – seeds are collected by animal to be eaten later

Epizoochory – seeds become attached to animal and become detached later

Synzoochory – seeds are collected by animal to be eaten later

Self-Dispersal Autochory In this type of dispersal the fruit may explodes releasing the seeds or may contain a trip mechanism that when stimulated release the seeds.
