Parts of a Flower

Flowers are abundant and range in colour, size, form, and anatomical arrangement. Each is beautiful growing singly or in cluster. However, most flowers have a uniform function, the reproduction of the species through the production of seed.

Flowers make seeds.

Each flower have essential organs of reproduction; there are two main flower parts: the male part (stamen) and the female part (pistil). Each flower also have essential accessory organs (sepals and petals). The sepals and petals attract pollinating insects.

The stamen has two parts: anthers and filaments. The anthers carry the pollen, which is yellow in colour and held up by the filament. The pistil has three parts: stigma, style and ovary. The stigma is the sticky surface at the the top of the pistil; it traps and holds the pollen. It is held up by a tube-like structure called the style. The style leads down to the ovary, which contains the ovules.
