A pollen holder is a structure found in the reproductive organs of flowering plants. It consists of four parts: an anther (6 letters), a pistil (6 letters), a SAC (3 letters), and a STAMEN (6 letters). The anther is a male reproductive organ that produces and stores pollen, while the pistil is the female reproductive organ that receives the pollen. The SAC is a small pouch that contains the pollen, and the STAMEN is a slender filament that supports the anther. Together, these four parts form the pollen holder, which is essential for the successful reproduction of flowering plants.
