A complete flower contains which of the following?

• A. Only petals and sepals
• B. Only stamens and carpels
• C. The petals are the primary floral organs
• D. All four floral organs: petals, sepals, stamens, and carpels

Answer: (D)

A complete flower has all four basic floral organ types: sepals, petals, stamens, and carpels. Sepals protect the developing bud, petals are usually colorful to attract pollinators, stamens are the male parts that produce pollen, and carpels (pistils) contain the ovules and later develop into fruit after fertilization. If any one of these parts is missing, the flower is incomplete. Saying petals are the primary floral organs is misleading because the four-part combination—including both protective and reproductive structures—defines completeness.
