(N/A) An ovule is a female megasporangium where the formation of megaspores takes place.
The various parts of an ovule are:
$1$. Funiculus: It is a stalk-like structure which represents the point of attachment of the ovule to the placenta of the ovary.
$2$. Hilum: It is the point where the body of the ovule is attached to the funiculus.
$3$. Integuments: These are the protective envelopes surrounding the ovule. They provide protection to the developing embryo.
$4$. Micropyle: It is a small opening or pore at the tip of the ovule formed by the projection of integuments. It marks the point where the pollen tube enters the ovule at the time of fertilization.
$5$. Nucellus: It is a mass of parenchymatous tissue enclosed within the integuments. The nucellus provides nutrition to the developing embryo sac.
$6$. Chalaza: It is the basal part of the ovule,representing the point of origin of the integuments.
