A) 100
B) 80
C) 40
D) 99
Correct Answer: A
Solution :
Wheat is an angiosperm plant. In this plant 80 grains (seeds) are produced by fertilization between 80 male and 80 female gametes. 80 male gametes i.e. pollen grains are produced by 20 meiosis in microspore mother cells while 80 female gametes i.e. megaspores are formed by 80 meiosis in megaspores mother cells because in angiosperm plants, after meiotic division in single megaspore mother cell, four megaspores are formed but only one megaspore is survived and other three get degenerated. Thus total meiotic divisions are 20 + 80 = 100.
