In [[seed plant]]s, the '''ovule''' is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''[[integument]]'', forming its outer layer, the ''nucellus'' (or remnant of the [[sporangium|megasporangium]]), and the female [[gametophyte]] (formed from a haploid [[megaspore]]) in its center. The female gametophyte — specifically termed a ''megagametophyte'' — is also called the ''embryo sac'' in [[Flowering plant|angiosperms]]. The megagametophyte produces an [[ovum|egg cell]] for the purpose of [[fertilization]]. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. On the basis of the relative position of micropyle, body of the ovule, chalaza and funicle, there are six types of ovules.
