Answer 2

Answer:

In a dioecious anther, each pollen sac contains 1000 micro spore mother cells. The total number of pollen grains produced by the anther in this case is 16000.

Explanation:

1 micro spore mother cell produces 4 pollen grains.

If one pollen sac contains 1000 micro spore 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 4*4000 = 16000 pollen grains.
