Sepals and the Corolla:
- Sepals are the outermost parts of a flower.
- They collectively form the calyx, which protects the flower bud and supports the petals.
- Sepals are usually green and often more leaf-like in appearance compared to petals.
- The corolla refers to the collection of petals.
- Petals are typically the colorful and attractive parts of a flower.
- The corolla is located inside the sepals.
- Together, the sepals and petals play a role in attracting pollinators.
So sepals are not collectively called the corolla. Sepals form the calyx, while the corolla refers to the petals of a flower.
