Final answer:
The ovary is the part of the carpel that encloses the ovules.
Step-by-step explanation:
The portion of a carpel that encloses the ovules is the ovary. A carpel consists of three main parts: the stigma, the style, and the ovary. The stigma is where pollen is deposited, the style is a tube-like structure that connects the stigma to the ovary, and the ovary is the enlarged structure at the base of the carpel that contains one or more ovules.Within the ovary, ovules develop into seeds after fertilization. The androecium or male reproductive organs, which includes the stamen with its filament and the anther where pollen grains develop, surrounds the central carpel.
