What is the male reproductive portion of a flower called?

The male reproductive portion of a flower is called the stamen. The stamen consists of two main parts: the anther and the filament. The anther is where pollen, which contains the male gametes, is produced. The filament supports the anther, elevating it to a position where pollinators or wind can facilitate the transfer of pollen to the female reproductive structures of the flower. This role of the stamen is crucial in the process of sexual reproduction in flowering plants, contributing to the formation of seeds and fruit.

The other components mentioned, such as the pistil, are involved in the female reproductive system of the flower, while petals and sepals serve primarily protective and aesthetic functions rather than reproductive ones. Understanding the distinct roles of these flower parts helps in grasping the overall reproductive strategies of flowering plants.
