9.3.2 Pollination and Fertilisation

Pollination refers to the transfer of pollen grains from the anther to the stigma

Fertilisation refers to the fusion of the male gamete nuclei with the female gamete to form a zygote. Pollen grains often contain an additional nuclei used in the fertilisation of the food store cells.

The Seed are the fertilised ovules. The seeds are moved away from the parental plant before germination to reduce competition for limited resources with parental plant. There are a variety of seed dispersal mechanisms including fruits, winds, water and animals.
