हिन्दीHow many meiotic divisions and how many pollen mother cells (PMCs) are required to produce 200 pollen grains in a typical angiosperm?
Correct answer · Option 1
50 meiotic divisions and 50 PMCs
Explanation
Each diploid pollen mother cell (PMC) undergoes one meiotic division to produce a microspore tetrad (4 microspores/pollen grains). Thus, to form 200 pollen grains, \( \frac{200}{4} = 50 \) PMCs and 50 meiotic divisions are required.
