A) two meiotic cell division
B) one mitotic cell division and two meiotic cell division
C) one meiotic cell division and two mitotic cell division
D) two meiotic cell division and one mitotic cell division
Correct Answer: C
Solution :
During microprogenesis, the sporogenous cells may directly act as microspore mother cells or pollen mother cells or PMCs. Each PMC, by a meiotic division, gives rise to a group of four haploid microspores, which are combined referred to as microspore tetrad. The first mitotic division in a pollen grain or microspore results into two unequal cells. The larger one is the vegetative cell, which eventually forms the pollen tube. The smaller one is the generative cells, which produce the mate gametophyte by another mitosis.
