If there are four cells in anthers, what will be the number of pollen grains?
Correct answer: A. 16
- A. 16
- B. 12
- C. 8
- D. 4
Explanation
Pollen grains or microspores are formed inside anther, which is the fertile portion of stamen or microsporophyll. Inside the anther, primary sporogenous cell gives rise to microspore mother cells or pollen mother cells (MMC or PMC). Each MMC on reduction division gives rise to 4 microspores or pollens. So, these four cells will give rise to 4 × 4 = 16 pollen grains.
