Female (♀) is the sex of an organism, or a part of an organism, that produces non-mobile ova (egg cells).
Some organisms that reproduce sexually can also reproduce asexually.
There is no single genetic mechanism behind sex differences in different species and the existence of two sexes seems to have evolved multiple times independently in different evolutionary lineages.
Other than the defining difference in the type of gamete produced, differences between males and females in one lineage cannot always be predicted by differences in another.
The concept is not limited to animals; egg cells are produced by chytrids, diatoms, water moulds and land plants, among others.
In land plants, female and male designate not only the egg- and sperm-producing organisms and structures, but also the structures of the sporophytes that give rise to male and female plants.
