Question

calculate the number of pollen grains in an anther.if the number of MMC/ Pmc in a microsporangium is 60.​

Answer 1

Explanation:

Total pollen sacs or microsporangia in bilobed dithecous anther =4

Each pollen sac has 100 microspore mother cells.

So total microspore mother cell in 4 pollen sacs=4X100=400

Meiosis produces 4 pollen grains or male gametophytes.

Meiosis in 400 microspore mother cell will produce=400X4=1600 pollen grains or male gametophytes.

So, the correct answer is '16000'
