What is the structure in flowers that produces pollen?

The structure in flowers that produces pollen is the anther. The anther is part of the stamen, which is the male reproductive organ of a flower. It is where pollen grains, which contain the male gametes, are synthesized and stored until they are released for pollination.

Understanding the function of the anther is key in the study of plant reproduction. Pollen must be transferred to the stigma of a flower for fertilization to occur, but it is the anther that is responsible for the production of this essential reproductive material. This distinction is important in horticulture, as pollination and seed production are integral to the cultivation of flowering plants.
