The anther is the part of a flower's stamen that contains and releases pollen. It typically sits atop a filament and plays a crucial role in plant reproduction by facilitating pollination.
Stamen: The male reproductive organ of a flower, consisting of a filament and an anther.
Pollen: Microscopic grains produced by anthers that carry male genetic material for fertilization.
