There are approximately over 369,400 species of flowering plants that exist in the wold today. Each species is unique but every flower will have the same key parts.

Some common parts of a plant that you will have heard of before include:
The stem, leaves, petal and roots.
Today we will look in more detail at the different parts of a flowering plants and their functions:

Pollen – Pollen looks a bit like dust and can be easily blown or moved around by the wind or insects within the same flower or to another flower. The flower will make pollen in the anther.

Pistil – This is the female part of the flower. It includes the style, stigma, ovary and ovules. It is in the pistil that fertilisation happens.

Stigma – The stigma is the female part of the flower. It is the sticky part at the top that stands up in the centre of the flower. It collects pollen from visiting insects, ready for fertilisation to happen.

Stamen – The stamen is the male part of the flower. It is a long part made up of the anthers and the filament. The stamen produces the pollen that then goes on to fertilise plants for reproduction.

Ovule – This is the part of the flower that gets fertilised and becomes a new seed.

Ovary – The bottom of the female part of the flower, where the ovules are. Ovules get fertilised and new seeds grow in the ovary.

Sepals – Sepals look like a cross between petals and leaves. They provide the flower and its petals with protection before they open out.
