Question:
A flower has 6 stamens out of which half are removed. The total number of male gametes produced from that flower if each lobe of its dithecous anther contains 26 pollen mother cells
A flower has 6 stamens out of which half are removed. The total number of male gametes produced from that flower if each lobe of its dithecous anther contains 26 pollen mother cells
Show Hint
For gamete calculation, remember the multiplication chain: stamens × lobes × PMCs × 4 (pollen) × 2 (gametes).

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Only 3 stamens remain (half of 6). Each anther has 2 lobes, and each lobe has 26 PMC, thus total PMCs = 3 × 2 × 26 = 156. Each PMC gives 4 pollen grains (male gametes), so 156 × 4 = 624 pollen grains. Each pollen grain contains 2 male gametes, so 624 × 2 = 1248 × 2 = 2496.
