What part of the stamen contains the pollen?

The anther is the part of the stamen that contains pollen. In flowering plants, the stamen is the male reproductive structure, which consists of two main parts: the filament and the anther. The filament is a slender stalk that supports the anther, allowing it to be positioned so that pollinators or wind can facilitate the transfer of pollen. The anther itself is where the pollen grains are produced and stored, making it crucial for the plant's reproductive process. Thus, understanding the role of the anther is essential in botany and for recognizing how plants reproduce sexually.
