Question

What is the maximum number of megaspores produced by an ovule?

• A. 1
• B. 2
• C. 5
• D. 4

Answer 1

The correct option is D

4

Similar to microsporogenesis, the diploid megaspore mother cell undergoes reduction division or meiosis to form a linear tetrad of haploid megaspores in most angiosperms. Out of these four megaspores, only the one closest to the chalazal end is functional and develops into the embryo sac while the other three degenerate.
