The group of sepals is called calyx.

The calyx is the outermost whorl of the flower, consisting of a group of sepals. Sepals are typically green, leaf-like structures that protect the developing flower bud. They are usually the first part of the flower to appear and are responsible for enclosing and protecting the other parts of the flower during the bud stage. Once the flower opens, the sepals often remain at the base of the flower.

Functions of the Calyx:
1. Protection: The calyx provides protection to the inner reproductive parts of the flower, including the petals, stamens, and pistils. It acts as a barrier against mechanical damage, insects, and other environmental factors.

2. Support: The sepals of the calyx provide support to the petals and other floral parts by holding them in place.

3. Photosynthesis: In some plants, the sepals of the calyx are green and capable of photosynthesis. They can produce food for the developing flower and contribute to the overall growth and development of the plant.

4. Attraction: In certain flowering plants, the sepals of the calyx may be brightly colored to attract pollinators. This is particularly true in species where the sepals are petal-like and resemble petals.

Composition of the Calyx:
The calyx is composed of sepals, which are modified leaves. They are usually green in color, but can also be colored or have a different texture depending on the species of the plant. Sepals are typically arranged in a whorl and may be fused or separate from each other.

Example:
Let's take the example of a rose flower. The calyx of a rose consists of five sepals that are green in color. The sepals protect the developing bud and provide support to the petals once the flower opens. The calyx may remain attached to the base of the flower even after the petals fall off.

In conclusion, the group of sepals in a flower is collectively called the calyx. It serves multiple functions including protection, support, photosynthesis, and attraction.
