Definition of Elaiosome

Elaiosome is a small structure that is being attached to a seed. Elaiosomes are composed of dead cells and they have a huge amount of lipids present in them. They also consist of other nutrients such s carbohydrates like starch, proteins, and certain vitamins. The most important function of an elaiosome in seeds is that it helps in the dispersal.


Ants are known to be the medium through which the seeds are dispersed. The ants feed on this elaiosome and the seed gets ditched in the heap of trash where it is able to germinate and grow into a new plant. They may also help the seeds to take water in and hydrate them so that germination can be initiated.
