Here's a breakdown:

* Ovary: This is the swollen base of the pistil, the female reproductive organ of a flower. Inside the ovary, you'll find one or more ovules.

* Ovules: These are the structures that contain the eggs, also known as female gametes.

During pollination, pollen grains land on the stigma (the top part of the pistil) and travel down a tube called the style to reach the ovary. Once there, fertilization occurs, and the ovules develop into seeds.
