Seed formation and seed dispersal
I can explain how seeds are formed and dispersed.
Lesson details
Key learning points
- Fertilisation occurs when pollen reaches the ovary of a 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 an anther is transferred to the stigma of a flower.
Ovary - Seeds are formed inside the ovary of a flower.
Fertilisation - Fertilisation happens when pollen from an anther reaches the 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.
