Why is the sepal important?
Function of Sepals
Protects the reproductive organs within the flower. In some plants with no petals, sepals function as petals. Safeguard the bud and flowers from harsh environmental conditions. Sepals protect both flowers and fruits by producing chemicals that would ward off predators.

Why do sepals protect the flower bud?
Sepals are modified leaves that encase or cover a flower bud as it develops. Sepals protect the delicate and intricate flower structures inside from drying out and being damaged by outside elements (rain, insects, etc.) until they mature.
What happens to the sepals as the flower opens?
During this time of formation, the sepals form a protective enclosure for the flower and keep it from drying out. Once the flower is completely formed, the sepals open. This allows the petals to spread and expose the inside of the flower. At this point, the sepals begin to serve different purposes.

In many flowers, the number of members of each whorl of the perianth is consistent and equal. Thus, a flower may have three sepals and three petals, or four sepals and four petals. There are many variations, however, including flowers with unequal numbers of parts per perianth whorl or no set number of perianth parts.
