They different parts of a flower are:

  • Androecium

  • Gynoecium

  • Calyx (accessory organ bearing sepals)

  • Corolla (accessory organ bearing petals)

Calyx − Calyx refers to the sepals.They are green in colour. They protect the plant in bud stage and also attract the insects for pollination.

Corolla − Corolla refers to the brightly coloured whorl of a flower. Individual unit of corolla is petals.Petals protect the inner essential organs (i.e., stamens and carpels)andattract pollinators since they are brightly coloured.

Androecium (male reproductive organ) − The androecium consists of whorls of stamen. The stamen consists of the filament (long and slender stalk) and anther (bilobed structure). A typical anther is bilobed, which contains the pollen grains.

Gynoecium (female reproductive organ) − Gynoecium represents the female reproductive part made up of carpels. Carpel is made up of:

  • Style − It connects stigma to the ovary.

  • Stigma − It acts as a receptacle for the pollen grains.

  • Ovary − It is the enlarged basal part on which style lies. Each ovary bears one or more ovules attached to cushion-like placenta. After fertilisation, ovules develop into seeds and ovary into fruit.
