Here's a breakdown:

* Ovary: The swollen base of a pistil (the female reproductive part of a flower).

* Seeds: Develop from the ovules (tiny structures within the ovary) after fertilization by pollen.

* Fertilization: The process where pollen from the male part of the flower (stamen) reaches the ovule and combines with its genetic material.

After fertilization, the ovary develops into a fruit, which often encloses the seeds and helps protect and disperse them.
