What part of the flower is responsible for producing pollen, which contains the male gametes?

The anther is the part of the flower that is responsible for producing pollen, which contains the male gametes. Located at the top of the stamen, the anther develops during the flower's reproductive phase and generates pollen grains through the process of meiosis. Each pollen grain contains the male gamete, which can fertilize the ovule in the ovary during the process of reproduction.

While other parts of the flower play crucial roles in the reproductive process, they do not produce pollen. The style connects the stigma to the ovary and serves primarily to support the stigma and facilitate the transfer of pollen. The stigma is the part of the flower that receives pollen during pollination, and it is not involved in pollen production. The ovary contains the ovules, which develop into seeds after fertilization but does not have any role in producing pollen. Therefore, the anther's specific function in pollen production makes it the correct answer.
