उत्तर
In angiosperms, one meiotic division of the megaspore mother cell leads to the formation of one egg. So, 300 egg cells are formed from 300 meiotic divisions. But one meiotic division of sperm leads to the formation of four haploid cells. So, 300 functional gametes will be formed by 300/4 = 75. So total meiotic divisions required are 375.
