Perianth is non reproductive part of flower and structure that forms an envelope surrounding the sexual organs consisting of the calyx and corolla
This statement is incorrect for
Monochlamydeous flower
Dichlamydeous flower
Trichlamydeous flower
Tetrachlamydeous flower
The perianth of dichlamydeous flowers is divided into two separate whorls: the outer whorl known as the calyx, which is made up of sepals, and the inner whorl known as the corolla, which is made up of petals. The perianth is made up of the calyx and corolla. The calyx and corolla can both protect the reproductive organs and attract pollinators. Hence, option b is the correct answer.
