The part of the plant that accepts the pollen and undergoes pollination is the stigma.

Here's a breakdown:

* Stigma: The sticky, often feathery top part of the pistil (the female reproductive part of a flower).

* Pollen: Tiny grains containing the male gametes (sperm) of a plant.

* Pollination: The process of transferring pollen from the anther (male part of a flower) to the stigma.

Once the pollen reaches the stigma, it germinates and grows a pollen tube down through the style (another part of the pistil) to the ovary, where fertilization can occur.
