If there are 4 pollen mother cells in anther, what will be the number of pollen grains?
16
During microsporogenesis, which takes place in the anther, each of the pollen mother cell (2n) undergoes meiotic cell division to produce a microspore tetrad. Each of the cell of microspore tetrad forms a pollen grain. Thus, from 4 cells, 16 pollen grains will be produced.
