Solution
Whorls of flower:
Along with the vegetative and reproductive parts, a flower is also composed of four whorls, which are largely responsible for the radial arrangement of a flower.
The flower is composed of four whorls: the calyx, corolla, androecium, and gynoecium.
Calyx:
Calyx is the outermost whorl composed of green, leaf-like structures called sepals.
Sepals enclose the inner parts of a flower and protect it in the bud stage.
Corolla:
Corolla is the second whorl of a flower composed of brightly colored parts called petals.
Petals attract insects for pollination.
Androecium:
Androecium is the third whorl inner to the corolla.
It represents the male reproductive part of the flower.
Gynoecium:
Gynoecium represents the female reproductive part of the flower.
It consists of a flask-shaped organ called a carpel.
Final answer: The four whorls of flower are calyx, corolla, androecium,andgynoecium.
