Did you know?

The flower of a plant will become the fruit.

However not all fruit are edible (can be eat).

Fertilisation in flowers

The process of fertilisation occurs when a male sex cell (in pollen grains) fuse with the female sex cell (in ovules) to for a zygote.


There are three stages for fertilisation to take place in a flowering plant.

  1. The pollen grains land on the stigma of a flower.
  2. A pollen tube grows from the stigma of a flower to the ovary.
  3. The pollen tube enters the ovule and the male sex cell fuses with the female sex cell to form a zygote.

After fertilisation

Once fertilisation has taken place, the flower starts to develop into a fruit.

The petals and sepals starts to dry up.

Inside the flower, the ovule starts to develop into a seed.

The ovary starts to become bigger and in edible fruits, usually become the fleshy part of the fruit.
