Sepals are leaf-like structures that are part of the outermost whorl of a flower and are generally green in color. They are found at the base of the flower, usually attached to the receptacle. Sepals collectively form the calyx, which often resembles a protective covering or bud shape.
One of the key functions of sepals is to enclose and protect the other parts of the flower during its development and before it blooms. They play a crucial role in protecting the tender floral bud from environmental factors such as extreme temperatures, insects, or physical damage.
Sepals vary in number, size, shape, and appearance depending on the species of plant. In some flowers, they are relatively small and inconspicuous, while in others, they can be large and showy, resembling petals. In such cases, the sepals may be brightly colored, attracting pollinators or acting as an additional visual cue for identifying the flower.
Although sepals are usually green, they can also adopt various other colors, including white, yellow, or even reddish shades. In certain flowers, the sepal color may serve as a distinguishing characteristic for the species.
Overall, the primary functions of sepals are protective and structural. They provide shielding for the other flower parts, aid in temperature regulation, and also contribute to the overall aesthetic appeal of the flower.
