Understand the structure of a flower: A flower is composed of several parts, including the petals, sepals, stamens (male reproductive structures), and carpels (female reproductive structures).
Identify the female reproductive structure: The carpel (or pistil) is the female part of the flower and consists of three main parts: the stigma, style, and ovary.
Define the ovary: The ovary is the enlarged basal portion of the carpel that contains the ovules, which are the structures that develop into seeds after fertilization.
Clarify the role of ovules: Ovules are the structures within the ovary that house the female gametophyte (embryo sac) and are fertilized by pollen to form seeds.
Conclude that the ovary is the correct answer: Among the options provided, the ovary is the part of the flower that contains the ovules, not the petal, anther, or stigma.
