A gamète (in Greek: γαμέτες ) is a reproductive cell of type Haploïde which finished the Méiose and cytoplasmic differentiation.
The gamètes resulting from germinal cells have varied structures. The female gamètes are generally bulky cells, containing many Cytoplasme and of Organite S. the male gamètes are small cells with the very reduced cytoplasm. They are most of the time mobile and capable of active displacement.
Animal kingdomAt the human one, like the majority of the animals, (except the Protozoon S), the female gamètes are the Ovule S and the male gamètes the Spermatozoïde S. the bodies producing the gamètes are called Gonade S. the formation of the gamètes is the Gamétogénèse: Spermatogenèse for the male gamètes, Ovogenesis for the female gamètes. The cellular division which takes place during the gamétogenèse and which makes pass the cell of the state Diploïde to the state Haploïde is the Méiose.
Vegetable kingdomAt the vegetable , the male gamètes are produced by the grain of Pollen and the gamète female door the name of Oosphère.
The meeting of the gamètes of the two sexes and, therefore, the return to the state diploïde are the Fécondation.
