What is a defining feature of sepals?

• A. Located at the base of the flower and surround and protect the bud
• B. Located above sepals; frequently brightly colored (attracts pollinators)
• C. The male reproductive structure that produces pollen
• D. The stem that supports the flower

Answer: (A)

Sepals form the outermost floral whorl, collectively called the calyx, and their main role is to protect the developing flower bud. They sit at the base of the flower, enclosing and shielding the bud before it opens. Petals are the colorful parts that attract pollinators and come after the sepals; stamens are the pollen-producing male structures; and the stem or stalk that supports the flower is the peduncle, not a floral organ. So the defining feature of sepals is their position and protective function around the bud at the base of the flower.
