Similarly to ordinary leaves, sepals are capable of performing photosynthesis. However, photosynthesis in sepals occurs at a slower rate than in ordinary leaves due to sepals having a lower stomatal density which limits the spaces for gas exchange.

What function do sepals have?

A Sepal Epidermis

The sepal is a defensive organ that encloses and protects the developing reproductive structures. At maturity, the sepal opens when the flower blooms.

Which part of flower helps in photosynthesis?

The leaf is the part of the flower responsible for making food for the process of photosynthesis. Carbon dioxide, water, and light are turned into glucose.
