Question

suppose each pollen sac contains 4 microspore mother cell find out total pollen formed from each anther​

Answer 1

Answer:

One pollen mother cell produces 4 haploid pollens. Hence, 20 pollen mother cells will produce 4 X 20 pollen grains that are equal to 80 pollen grains. Each pollen grain produces 2 male gametes. 80 X 2 = 160 male gametes. Now, mustard is Dithecous, hence each stamen has 4 microsporangia. Therefore 160 x 4 = 640 male gametes per stamen. In a mustard flower, there are 6 stamens which means, 640 x 6 = 3840 male gametes in total.
