Here's why:

* Ovary: The ovary is the base of the pistil, the female reproductive part of the flower. It contains the ovules, which are the potential seeds.

* Fertilization: When pollen from the stamen (male part) fertilizes the ovule, the ovary begins to swell and develop.

* Fruit Formation: The ovary, now containing the fertilized ovules (seeds), develops into the fruit. The fruit serves to protect and nourish the developing seeds until they are ready for dispersal.

So, the next time you enjoy a piece of fruit, remember that you're eating the transformed ovary of a flower!
