Which term describes the outermost floral whorl of a flower, consisting of sepals?

• A. Gynoecium
• B. Sepal
• C. Corolla
• D. Calyx

Answer: (D)

In flowering plants, the parts of a flower are arranged in circular whorls. The outermost ring is made up of sepals, and when we refer to that entire outer ring as a group, it is called the calyx. Sepals are the individual members of this whorl, the calyx being their collective name. The calyx often protects the developing bud and can help support the flower, sometimes being green and leaf-like but in some species colorful. The other terms describe different whorls: the corolla is the inner ring of petals, the gynoecium is the female reproductive part, and a lone sepal would indicate a single member rather than the whole outer whorl.
