ANSWER
The different parts of a flower are:
1. Androecium (male reproductive organ) - The androecium consists of whorls of the 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.
2. Gynoecium (female reproductive organ) - Gynoecium represents the female reproductive part made up of carpels. The carpel is made up of:
Style - It connects the 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 the cushion-like placenta. After fertilisation, ovules develop into seeds and ovary into a fruit.
3. Calyx (accessory organ bearing sepals) - Calyx refers to the sepals. They are green in colour. They protect the plant in the bud stage and also attract the insects for pollination.
4.Corolla (accessory organ bearing petals) - Corolla refers to the brightly coloured whorl of a flower. The individual unit of the corolla is petals. Petals protect the inner essential organs (i.e., stamens and carpels) and attract pollinators since they are brightly coloured.

Parts of a Flower and their Functions
Many flowers have male parts and female parts.
Male part – Stamen
The stamen has two parts
Anthers – Pollen producing part Filaments – They hold up the anthersFemale part – Pistil
The pistil has three parts
Stigma – Sticky surface at the pistil’s top, where the pollen germinates Style – Holds up the stigma Ovary – Contains the ovules Ovules – Become the seed after fertilization by pollen Other Parts of the Flower Petals – Usually bright, to attract pollinators Sepals – Protect the flower bud when it is developing Receptacle – Portion of the stalk with the flower structure Peduncle – Flower stalk
