The body of the ovule is fused within the funicle at

The structure of the ovule can be studied under the following headings:
a) Funicle: The stalk of the ovule by which it remains attached to the placenta.
b) Hilum: It is the junction between ovule and funicle or the point of attachment of funiculus to the body of ovule.
c) Integument: The one or more protective envelops surrounding the body of the ovule.
d) Micropyle: The pore or passage present at the tip of the ovule where the integument is absent.
e) Chalaza: Opposite to micropylar end representing the basal part of the ovule.
f) Nucellus: The parenchymatous mass of tissue enclosed within the integuments and forms the body of the ovule.
g) Embryo sac: It is also called the female gametophyte and is located in the nucellus. An ovule generally has a single embryo sac formed from a megaspore.
