Definition of Term

(English) Cell which develops into an ovum. Oogonia become oocytes when meiosis begins and specialised cells surround each oocyte to form a follicle. The oocyte undergoes a maturation in preparation for spawning as an egg. The nucleus enlarges and its membrane becomes irregular, the cytoplasm becomes vacuolated, yolk is deposited and a zona radiata develops around the oocyte. (See also: ovum, cell, zygote)
(French) Cellule qui se développe dans un ovaire. (See also: ovum, cell, zygote)
(Portuguese) Célula que dá origem ao óvulo. (See also: ovum, cell, zygote)
