Answers
Answer:
The calyx is a sepal present in the outer whorl of a flower that is green in color and protects the flower. Based on the calyx, flowers are of two types- Gamosepalous and polysepalous. Gamosepalous is a condition in which sepals are fused or united whereas in Polysepalous sepals are free.
In gamosepalous flowers, the calyx consists of fused sepals. The calyx is the term given to all the sepals collectively of the same plant. The sepals refer to a leaf-shaped structure found in flowering plants or angiosperms. It is a modified leaf present on the outermost part of the flower. The main function of sepals is to give support and protection to a flower bud when it's closed around it until it’s ready to bloom. Sepals can be of a wide variety, from long to short, thick to thin, fused together or separated, and are found in different numbers. These fused together sepals are found in gamosepalous flowers. Example- Periwinkle and Hibiscus.
