Stamens with prominent anthers carrying
pollen The stamen is a male reproductive organ of a flower. It produces the pollen. The stamen has two parts: anther and stalk. The stalk is also called a filament.
The anther contains microsporangia. Each microsporangium contains pollen mother cells. These undergo meiosis, and produce pollen grains, which contain the male gametes (sperm).
The pollen grains are actually haploid male gametophytes.
