Species that are divided into females and males are classified as gonochoric in animals, as dioecious in seed plants and as dioicous in cryptogams. 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. The concept is not limited to animals egg cells are produced by chytrids, diatoms, water moulds and land plants, among others. 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. There is an argument that this pattern was driven by the physical constraints on the mechanisms by which two gametes get together as required for sexual reproduction. Oogamous species, which include humans, in which the female gamete is much larger than the male and has no ability to move.Anisogamous species with gametes of male and female types,.Isogamous species with two or more mating types with gametes of identical form and behavior (but different at the molecular level),.Generally, a female cannot reproduce sexually without access to the gametes of a male, and vice versa, but in some species females can reproduce by themselves asexually, for example via parthenogenesis. Defining characteristicsДЇemales produce ova, the larger gametes in a heterogamous reproduction system, while the smaller and usually motile gametes, the spermatozoa, are produced by males. Female can refer to either sex or gender, or even the shape of connectors, such as screws, or electrical and technical equipment. The word female comes from the Latin femella, the diminutive form of femina, meaning ' woman' it is not etymologically related to the word male, but in the late 14th century the spelling was altered in English to parallel the spelling of male. 'fГ¦mnan,' an Old English word for 'female' In humans, the word female can also be used to refer to gender. Female characteristics vary between different species with some species having pronounced female characteristics, such as the presence of pronounced mammary glands in mammals. Most female mammals, including female humans, have two X chromosomes.

In species that have males and females, sex-determination is based on either chromosomes, or environmental conditions. The exact mechanism of female gamete evolution remains unknown. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. It also stands for the planet Venus and is the alchemical symbol for copper.ДЇemale (symbol: в™Ђ) is the sex of an organism that produces the large non-motile ova (egg cells), the type of gamete (sex cell) that fuses with the male gamete during sexual reproduction. The symbol of the Roman goddess Venus is used to represent the female sex in biology.
