Lesson details
Key learning points
- Fertilisation occurs when pollen reaches the ovary of another flower.
- A seed is formed once a plant has been fertilised.
- Seed dispersal allows plants to spread out and avoid competing with one another for the same resources.
- Seeds can be scattered by wind, water, animals or explosion. This is called seed dispersal.
Keywords
Pollination - Pollination is when pollen from a male anther is transferred to the female stigma of a flower.
Ovary - Seeds are formed inside the ovary of a flower.
Fertilisation - Fertilisation happens when pollen from a male anther reaches a female ovary in a flower.
Seed formation - Seed formation happens inside flowers after a plant has been fertilised.
Seed dispersal - Seed dispersal is the way seeds are spread out from their parent plant.
Common misconception
Pupils may confuse pollen and seeds or think that pollen that is dispersed by the wind can grow into a new plant if it lands on soil.
Explain that pollen is different from seeds as pollen cannot grow into a new plant. It plays a part in fertilisation, which leads to seed formation, but is not a seed and cannot turn into seeds.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
