Question

Female gametophyte of angiosperms is represented by

• A. Ovule
• B. Megaspore mother cell
• C. Embryo sac
• D. Nucellus

Answer 1

The correct option is C Embryo sac

•Ovule is the megasporangium along with its protective coverings.

•Megaspore mother cell is the diploid cell which undergoes meiosis to form four haploid megaspores. Three of the megaspores degenerate and one remains functional.

•Embryo sac or the female gametophyte is formed from the functional megaspore by the process of megagametogenesis.

•Nucellus is the central part of the ovule in which embryo sac is present. Nucellus forms bulk of the ovule and has nutritive function.

Thus, female gametophyte of angiosperms is represented by the embryo sac.

So, the correct answer is C.
