Answer: The following are the main components of an anatropous (ovule):
(I) The hilum is the point where the ovule and funicle meet.
(ii) Integuments are protective envelopes that surround each ovule.
(iii)Micropyle is a missing integument opening presentation at the tip.
(iv) Chalaza is the micropylar end of the ovule that communicates with the ovule’s basal component.
(v) The integuments encase the nucellus, a mass of cells with sustenance holds.
(vi) The nucellus contains the embryo sac or female gametophyte (by and large one framed from a megaspore through reductional).
