Question

Where is an embryo sac found in female reproductive part of flower?

Answer 1

In seed plants, ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: The integument(s) forming its outer layer(s), the nucellus (or remnant of the megasporangium) and female gametophyte (formed from haploid megaspore) in its center. The female gametophyte specifically termed a mega gametophyte is also called the embryo sac in angiosperms.
