In a dithecous anther, each pollen sac contains 1000 MMC.
What is the total number of pollen-grains produced by the anther?
- A 4000
- B 8000
- C 16000
- D 32000
Answer & Solution
Correct Answer
(C) 16000
Step-by-step Solution
Detailed explanation
(C) 16000,
1 microspore mother cell produces 4 pollen grains. If one pollen sac contains 1000 microspore mother cells, then pollens produced are 4000.
In a dioecious anther, there are 4 pollen sacs so in total the number of pollen grains produced in 4 pollen sacs is 4x4000-16000 pollen grains.
