HORTICULTURE

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: -The male part of flowering plants is the stamen. This consists of an anther supported by a single stalk, the filament. The anther usually contains four pollen sacs which are responsible for producing pollen grains.

Detailed explanation-3: -Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.

Detailed explanation-4: -Microsporogenesis is the process of development and formation of pollen grains in the anther of the stamen.

Detailed explanation-5: -Stamens are the male reproductive structure of the plant. They produce pollen grain by the process of microsporogenesis.
