Carpels

The carpel is the female part of the flower, where the seeds are made. The carpel has three parts: the stigma, the style, and the ovary.

  • The stigma is covered in a sticky substance. Its job is to "catch" the grains of pollen (which usually come from another flower).

  • The style is the stalk that holds up the stigma.

  • The ovary contains the ovules (or "eggs").

When the flower is pollinated, the pollen sticks to the stigma. It then travels down the style to the ovary. In the ovary, the pollen joins with the ovules, and the ovules become seeds. This is called fertilisation. After fertilisation, the ovary turns into the fruit.
