The calyx is referred to as the outermost whorl of a flower. The calyx, found at the base of many flower species, is comprised leaf-like structures and protects the flower while it is developing. These sepals are often the same number as the petals. While calyces are usually green, the calyx is either a similar colour or a completely different colour.
The calyx is located just beneath the corolla. When identical and indistinguishable, the perianth is used for a plant’s calyx and corolla. The calyx continues to support fruit growth after the flower has bloomed.
The calyx plays an essential function for the flowering plant. It protects and prevents the drying out of the developing flower. It is tightly compressed into a bud. The only part of a flower visible in bud form is its outer covering or sepals.
