Pollen-pistil interaction:- Pollen-pistil interaction refers to the intricate biological process that occurs in flowering plants during sexual reproduction. It involves the interaction between pollen, which carries the male gametes (sperm cells), and the pistil, the female reproductive organ of a flower. This interaction is essential for fertilization to take place, leading to the formation of seeds and the continuation of the plant species. The pollen must land on the pistil, germinate, and grow a pollen tube to deliver its sperm cells to the ovule, where fertilization occurs. This process can involve various mechanisms, such as pollen recognition by the pistil and molecular signaling for successful reproduction.
