If each microsporangium contains 75 pollen mother cells (PMCs), what is the maximum number of pollen grains produced by a Datura flower?
6000
No. of PMCs present in microsporangium = 75
No. of pollen grains produced on meiosis = 75 × 4 = 300
No. of pollen grains produced by dithecous anther = 300 × 4
No. of pollen grains produced by one stamen (tetrasporangiate) = 1200
Total no. of pollen grains produced by 5 stamens = 1200 × 5
(Datura flower has 5 stamens) = 6000
