Question

A typical bilobed tetrasporangiate anther has 25
pollen mother cells per microsporangium. How many
total male gametes can be formed from this anther?​

Answer 1

Answer:

800 male gametes formed.

Explanation:

There are 4 microsporangia ( tetrasporangiate) each containing 25 pollen mother cells.

so, 25 × 4 =100 pollen mother cells are present in bilobed anther.

1 pollen mother cell produces 4 pollen grains by meiosis.

so, 100 pollen mother cells produce 100×4 = 400 pollen grains.

1pollen grain produces 2 male gametes by mitosis of generative cell inside pollen grain.

so, 400 pollen grains produces 400×2 = 800 male gametes.
