Pollination and fertilisation
I can describe the processes of pollination and fertilisation in flowering plants.
Lesson details
Key learning points
- Pollination is the transfer of pollen from the male anther to the female stigma.
- There are two types of pollination; self-pollination and cross-pollination. The latter increases variation in a species.
- Pollen grains can be transferred by the wind, water or by insects.
- Fertilisation is the fusion of the nuclei from the male and the female gametes.
- A zygote grows into an embryo and then a new plant.
Common misconception
Pollen are seeds, or that seeds are not made by sexual reproduction.
Clearly show the difference between pollen as a gamete and the seeds as the offspring that grows into a new plant.
Keywords

Ovary - The ovary is a female organ of the flower where ovules produce ova.
Style - The style holds the stigma and connects it to the ovary.
Stamen - The stamen is the male part of the flower, made up of an anther held up by a filament.
Fertilisation - The fusion of a male gamete (from pollen) and a female gamete (an ovum) is called fertilisation.
