Which part of a flower is primarily responsible for pollen production?

The anther is the part of a flower that is primarily responsible for pollen production. It is located at the tip of the stamen, which is the male reproductive structure of the flower. The anther produces pollen grains, which contain the male gametes needed for fertilization. During the process of pollination, this pollen can be transferred to the stigma of a flower, which is part of the pistil—the female reproductive structure of the flower.

The stigma acts as the receptive surface for pollen but does not produce it. The style is simply a tubular structure that connects the stigma to the ovary, where ovules are produced. The pistil encompasses the stigma, style, and ovary as a whole but is not specifically responsible for the production of pollen. Thus, understanding the role of the anther within the reproductive process of flowering plants highlights its critical function in sexual reproduction.
