CAIE IGCSE Biology 16.3.6 Fertilisation occurs when a pollen
Practise sequencing events after pollination, locating fertilisation in flower diagrams, and naming the ovule as the female gamete site.
How this is tested
- sequence pollen landing on stigma, pollen tube growth through style and entry into the ovule
- mark fertilisation in the ovary on a flower diagram and name the ovule as the gamete site
- state that fertilisation is fusion of the pollen nucleus with a nucleus in an ovule
