What is the Difference Between Calyx and Corolla?

The main difference between calyx and corolla lies in their structure, color, and function. Here are the key differences between the two:

1. Structure: Calyx is made up of green leaf-like structures called sepals, while corolla is made up of brightly colored parts known as petals. The calyx is leaf-like, and the corolla is petaloid.
2. Color: Calyx is generally green in color, while corolla has bright colors.
3. Function: Calyx protects the flower in the bud stage, while corolla attracts insects for pollination. The calyx provides structural support to the flower, and the corolla protects the reproductive organs of the flower.
4. Size: The sepals of the calyx are usually small, while the petals of the corolla are large.
5. Position: Calyx is the outermost whorl of a flower, and corolla is the second outermost whorl in the flower.

In summary, the calyx is the outermost whorl of a flower, consisting of sepals that protect the developing flower and provide structural support. On the other hand, the corolla is the inner whorl, made up of colorful petals that protect the reproductive organs of the flower and attract pollinators.

Comparative Table: Calyx vs Corolla

The main differences between the calyx and corolla in flowers are summarized in the following table:

In summary, the calyx is the outermost whorl of a flower and is composed of sepals, which are often green and protect the inner whorls of the flower in the bud stage. The corolla, on the other hand, is the second whorl of the flower and is composed of petals, which are usually brightly colored to attract insects for pollination and protect the reproductive organs of the flower.
