The structure of a flower.

Sepals enclose the flower, petals may be brightly colored to attract pollinators.

Stamens produce pollen, and carpels contain ovaries.

An ovary caontains several ovules which develop into seeds after fertilization.

The stamens collectively are called "androecium", while the carpels are called "gynoecium".

A complete flower has all four basic floral organs.

A perfect flower contains both male and female structures.
