b. Calyx, corolla, gynoecium and androecium

Answers (1)

The answer is option (a) Calyx, corolla, androecium, and gynoecium

The sequence of four whorls is- calyx, corolla, androecium and gynoecium.

The calyx is the outer protective layer of a flower, consisting of sepals that shield the flower bud before it opens. The corolla is the term for the flower’s petals, which are designed to attract pollinators through their color and fragrance, aiding in pollination. The androecium refers to the male reproductive organs, specifically the stamens, which produce and release pollen. The gynoecium is the female reproductive structure, including the stigma (where pollen is received), the style (connecting to the ovary), and the ovary itself, which contains the ovules. These components work together to facilitate pollination, fertilization, and seed formation.
