Question

How many meiotic divisions will be needed to produce 44 female gametophytes in angiosperms ?

Options

• 11

• 22

• 44

• 66

Answer 1

44

 The female gametophyte develops from megaspore mother cell by meiotic division during the process of megasporogenesis. The meiosis in the megaspore mother cell produces four haploid megaspores out of which three degenerate and only one matures to form the functional female gametophyte. Thus to produce 44 female gametophytes, 44 meiotic divisions are needed.
