In 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.
The answer is the option (b) Diploid
Since no meiosis takes place, so no change in ploidy will take place.
