What is the term for the part of a flower that consists of the petals and encloses the stamens and pistil?

• A. Petals
• B. Sepals
• C. Corolla
• D. Stamen

Answer: (C)

The corolla is the collective structure made up of petals that surrounds and helps enclose the inner reproductive parts of the flower, the stamens and pistil. This arrangement makes the petals the visible, colorful part that attracts pollinators, while the reproductive organs stay protected inside. The outer ring formed by sepals is called the calyx and serves mainly to protect the bud, not to enclose the petals themselves. A single petal isn’t the enclosing structure, and the stamens and pistil are the reproductive organs, not the enclosing petals. So the term that fits this description is corolla.
