Question

In a flower, if the megaspore mother cell forms megaspores without undergoing meiosis and if one of the megaspores develops into an embryo sac, its nuclei would be.

• A. Haploid
• B. Diploid
• C. A few haploid and a few diploid
• D. With varying ploidy

Answer 1

The correct option is B Diploid

Meiosis is the reductional division and this occurs in the megaspore mother cell so that the diploid cell divide and form a haploid gamete. If the megaspore mother cell does not undergo meiosis then the ploidy of the embryo sac will be 2n or diploid.

So, the correct option is 'Diploid'
