Pollination is the process by which pollen is transferred from the male reproductive organ to what structure in a flower?

• A. The stigma of a compatible flower
• B. The leaf blade
• C. The root system
• D. The ovary

Answer: (A)

Pollination is about moving pollen from the male parts to the female parts so fertilization can occur. In flowering plants, pollen grains produced in the anthers must land on the stigma, the receptive surface of the pistil. On the stigma, the pollen hydrates and germinates, forming a pollen tube that grows down the style to reach the ovary and fertilize the ovules. The leaf blade and root system aren’t involved in this transfer, and while fertilization happens in the ovary after the pollen tube reaches it, the initial transfer occurs to the stigma.
