DENDROLOGY

Detailed explanation-1: -Through the process of meiosis, pollen is formed in the pollen sacs (microsporangia) inside the anthers of a flower. The anther, while it is developing from anther primordium (undifferentiated cells), forms two clusters of cells.

Detailed explanation-2: -Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.

Detailed explanation-3: -Microsporogenesis is the process of development and formation of pollen grains in the anther of the stamen.

Detailed explanation-4: -One pollen mother cell produces 4 pollen grains in plants. So if there are 1200 total pollen grains then there would have been originally 300 pollen mother cells. Q. An anther has 1200 pollen grains.
