What part of the plant is responsible for holding pollen?

The part of the plant responsible for holding pollen is the anther. Located at the tip of the stamen, which is the male reproductive structure of a flower, the anther develops and releases pollen grains that contain male gametes. During the process of pollination, this pollen can be transferred to the stigma of a pistil from another flower, facilitating fertilization and the production of seeds.

The filament is a slender stalk that supports the anther but does not hold pollen itself. The pistil is the female reproductive part of the flower, consisting of the stigma, style, and ovary, but is not involved in the production or holding of pollen. The stamen comprises both the anther and filament but isn't the specific structure that holds the pollen; it's the anther that performs that essential function.
