What is the function of sepals in a flower?

Sepals have a crucial role in the development of a flower. Their primary function is to protect the flower bud before it opens. They typically encase and shield the developing petals and reproductive structures from environmental hazards, pests, and physical damage. As the flower matures and prepares for blooming, the sepals may also support the petals and provide stability to the entire floral structure.

While attracting pollinators is an essential function of the petals, producing pollen is the role of the stamen, and serving as the reproductive structure is the function of the ovary and other components of the flower. Therefore, the primary function of sepals is protection, which makes the provided answer accurate in the context of flower anatomy.
