Which part of carpel, in an angiospermic flower, bears ovules?

Ovary

The part of carpel that bears ovules is the ovary. The ovary is the swollen base of the carpel, and it is where the ovules are produced. The ovules are contained in structures called locules, which are chambers within the ovary.

The stigma is the top of the carpel, and it is where the pollen grains land. The style is the tube that connects the stigma to the ovary. The thalamus is the receptacle of the flower, and it is the part of the flower that supports the other parts.
