What role do anthers play in flowering plants?

Anthers play a crucial role in the reproductive system of flowering plants by producing pollen. Pollen is the male gametophyte and is essential for fertilization, as it contains the male sperm cells needed to fertilize the ovules found in the ovary of the flower. During the process of pollination, the pollen grains are transferred from the anthers to the stigma of a compatible flower, which can lead to fertilization and the development of seeds. This essential function of producing and releasing pollen makes anthers a key component in the reproductive cycle of angiosperms (flowering plants).

While attracting pollinators, supporting the ovary, and protecting seeds are important aspects of a plant’s reproductive strategy, they are not the direct functions of the anthers themselves. Attracting pollinators relates more to the petals and overall flower morphology. Supporting the ovary is primarily the function of the flower's structure, while protecting seeds relates to the role of surrounding structures like fruits.
