What is the primary function of the calyx in a flower?

• A. The calyx is composed of petals.
• B. The calyx produces pollen.
• C. The calyx, made of sepals, protects the developing bud.
• D. The calyx develops into fruit.

Answer: (C)

The calyx serves as the outer protective layer for a flower bud. It’s made up of sepals, which are leaflike structures that wrap around and shield the delicate developing parts of the flower from damage and water loss as the bud forms and before it opens. This protective role is what makes it the best answer. Pollen production comes from the stamens, not the calyx, and the petals form the colorful inner ring (the corolla) to attract pollinators. The fruit develops from the ovary after fertilization, not from the calyx. So protecting the developing bud is the primary function of the calyx.
