Describe about pistil (gynoecium).

The gynoecium represents the female reproductive part of the flower.

The gynoecium may consist of a single pistil (monocarpellary) or may have more than one pistil (multicarpellary).

When there are more than one the pistils may be fused together (syncarpous) or may be free (apocarpous) structure of pistil.

Each pistil has three parts the stigma, style and ovary.

Stigma : The stigma serves as a landing platform for pollen grains.

Style : The style is the elongated slender part beneath the stigma.

Ovary : The basal bulged part of the pistil is the ovary.

Placenta : It is located inside the ovarian cavity. Arising from the placenta are the megasporangia, commonly called ovules. The number of ovules in an ovary may be one (wheat, paddy, mango) to many (papaya, watermelon, orchids).
