What is the male part of the flower that produces pollen?

The male part of the flower that produces pollen is the anther. Within the flower's structure, the anther is located at the tip of the stamen, which is the male reproductive organ. The anther is specifically designed to produce and release pollen grains, which contain the male gametes (sperm cells) necessary for fertilization.

Understanding the role of the anther is crucial in the context of plant reproduction, as pollen must be transferred to the female part of the flower for successful fertilization and seed development. In contrast, the stigma is part of the female reproductive organ that receives pollen, the filament is the supporting stalk of the stamen that holds the anther, and the ovary is part of the female reproductive system that contains the ovules, which develop into seeds after fertilization occurs. This differentiation of parts is key in the reproductive processes of flowering plants.
