Differentiate Corolla and calyx
Answers
Answer:
The main difference between calyx and corolla is that calyx is the whorl of sepals of a flower whereas corolla is the whorl of petals. Furthermore, calyx forms the outermost layer of the flower while corolla is the whorl that occurs in the inner side of the calyx.
Calyx and corolla are two whorls of modified leaves, serving as the structures of a flower. They are collectively known as the perianth. Moreover, calyx protects the internal structures of the flower bud while corolla attracts pollinators to the flower.
Answer:
The key difference between calyx and corolla is that calyx is the collection of sepals while the corolla is the collection of petals of a flower.
Flowers are the reproductive structures of flowering plants. They have several parts – petals, sepals, stamen, and carpel are the main parts. Each part performs distinct functions. Complete flowers have all four parts, while incomplete flowers lack one or more parts. The carpel is the female reproductive organ of the flower while stamens are the male reproductive organs. Petals are the most colourful parts. They surround the reproductive organs. Petals are collectively called the corolla. Corolla helps to attract pollinators. Sepals are modified leaves that enclose the developing flower. Sepals are collectively called the calyx. Calyx protects the flower bud. It also provides structural support to a flower.
What is Calyx?
The calyx is the outermost whorl of the flower composed of sepals. Therefore, the collection of sepals is known as the calyx. The sepal is the unit of the calyx. Calyx is mostly green in colour. It has a leaf-like structure. The calyx is present just beneath the corolla. Together, the calyx and corolla is called the perianth. Calyx protects the flower bud and the developing flower. Especially, it protects the petals and supports petals when blooming.

Moreover, calyx provides structural support to the flower. After flowering, calyx has no more use. In some flowers, the sepals are fused towards the base, forming a calyx tube.
What is Corolla?
Petals are the modified leaves which are colourful. They protect the reproductive parts of the flower. Collection of petals of a flower is called the corolla. Therefore, the petal is the unit of a corolla. Corolla is brightly colourful in almost all flowers. Since corolla is colourful, it helps the flower to attract pollinators such as birds and insects.

Moreover, in many flowers, the corolla produces different scents to attract pollinators. Shape and the size of the corolla also influence pollination. A large corolla is visible for a large distance for pollinators. Corolla is present just above the calyx
