Botany - Sexual Reproduction in Flowering Plants Question with Solution | TestHub

200 zygote are produced when 200 male gamete fuses with 200 eggs. Micropore mother cell undergoes meiotic division to produce microspore tetrads that dissociate to form 4 pollen grains. Similarly, Megaspore's mother cell undergoes meiotic division to form 4 megaspores but only one remains functional while the other three degenerate. Hence, to produce 200 male gametes 50 meiotic division is required whereas to produce 200 egg 200 meiotic division is required. So the total number of meiotic divisions required to produce 200 zygotes is 250
