Each stamen which represents the male reproductive organ consists of a stalk or a filament and an anther.
An actinomorphic flower can be dissected into two equal halves from any plane.
Superior ovary is found in hypogynous flowers.
When stamens are attached to the petals, they are epiphyllous as in brinjal.

It is the female reproductive part of the flower.
It is composed of stamens.
Stigma is usually at the tip of the style and is the receptive surface for pollen grains.
Each ovary bears one or more ovules attached to a flattened, cushion like placenta.
