Question

Number of meiosis required to produce 100 functional megaspore in angiosperm?

A) 125

B)100

C)25

D)75

Answer 1

In angiosperms, 1 meiotic division of Megaspore mother cell leads to production of four haploid megaspores. In gymnosperms and most flowering plants, only one of the four megaspores is functional at maturity, and the other three soon degenerate.
Thus to produce 100 functional megaspore, 100 meiosis must be needed.
Option (B) is correct.
