Plant reproduction
Flowers are important for sexual reproduction by plants. They produce male sex cells and female sex cells. These must meet for reproduction to begin, a process called pollination.

Parts of a flower
The flower is the reproductive organ of many plants.
The table describes the main parts of a flower and their functions:
| Structure | Function |
|---|---|
| Sepals | Protect the unopened flower |
| Petals | May be brightly coloured to attract insects |
| Stamens | The male parts of the flower (each consists of an anther held up on a filament) |
| Anthers | Produce male sex cells (pollen grains) |
| Stigma | The top of the female part of the flower which collects pollen grains |
| Ovary | Produces the female sex cells (contained in the ovules) |
| Nectary | Produce a sugary solution called nectar, which attracts insects |
