Structure of Flower

Flowers are an important part of the reproductive system of plants. The particular color, pattern or scent of a flower attracts the appropriate pollinators like birds and insects.

This helps in the process of pollination.

Flower Part	Form and Function
Peduncle	Flower stalk.
Receptacle	Part of flower stalk bearing the floral organs, at base of flower.
Sepal	Leaf-like structures at flower base, protects young flower bud.
Calyx	All the sepals together form the calyx.
Petal	Located in and above the sepals, often large and colourful, sometimes scented, sometimes producing nectar. Often serve to attract pollinators to the plant.
Corolla	All the petals together form the corolla.
Stamen	Male part of the flower, consisting of the anther and filament, makes pollen grains.
Filament	The stalk of the stamen which bears the anther.
Anther	The pollen bearing portion of a stamen.
Pollen	Grains containing the male gametes. Immature male gametophyte with a protective outer covering.
Carpel\Pistil	Female part of the flower. Consisting of the stigma, style and ovary.
Stigma	Often sticky top of carpel, serves as a receptive surface for pollen grains.
Style	The stalk of a carpel, between the stigma and the ovary, through which the pollen tube grows.
Ovary	Enlarged base of the carpel containing the ovule or ovules. The ovary matures to become a fruit.
Ovule	Located in the ovaries. Carries female gametes. Ovules become seeds on fertilization.

The female reproductive part of a flower is the pistil.

It consists of three parts – the stigma, the style and the ovary.

Like the stamens, the number of pistils also varies from flower to flower.

The stamen is the male reproductive part of a flower.

Like sepals and petals, every flowering plant differs in the number of stamens, too

The small tube with a little bulge at the end of a stamen is called the filament.

The filament has a yellow sac called the anther.
