Here's a breakdown:

* Stigma: The sticky, often feathery top part of the pistil (female reproductive organ). It's designed to catch pollen grains.

* Style: The stalk-like structure connecting the stigma to the ovary.

* Ovary: The base of the pistil where the ovules (potential seeds) are located.

Once pollen lands on the stigma, it germinates and sends a pollen tube down through the style to reach the ovary. The pollen tube carries the male gametes (sperm) to fertilize the ovules within the ovary, ultimately leading to seed formation.
