HORTICULTURE

Detailed explanation-1: -Explanation: Stamens are the male reproductive structure of the plant. They produce pollen grain by the process of microsporogenesis.

Detailed explanation-2: -Stamens: Male Reproductive Organs A stamen consists of an anther (which produces pollen, the male reproductive cell) and a filament.

Detailed explanation-3: -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. Each pollen grain is a single cell containing two male gametes.

Detailed explanation-4: -The male reproductive structures include the anther and filament. The anther is the structure where production and release of pollen grains occur.

Detailed explanation-5: -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.
