Lesson details

Key learning points

  1. Plants reproduce to make new plants (offspring) in different ways.
  2. Flowering plants can reproduce by making seeds, which grow into new plants.
  3. Pollination is the transfer of pollen from the anther of one flower to the stigma of another flower.
  4. After pollination, pollen travels to the ovary and fertilises the flower.
  5. Seed formation happens after fertilisation.

Keywords

  • Reproduce - When living things reproduce they create offspring.

  • Anther - An anther is a male part of a flower that produces pollen.

  • Stigma - The stigma is a sticky part at the top of the female part of a flower.

  • Ovary - Seeds are formed inside the ovary of a flower.

  • Pollination - Pollination is the transfer of pollen from the anther of one flower to the stigma of another flower of the same species.

Common misconception

Pupils may think that plants make seeds automatically as a part of their life cycle, rather than needing pollination to take place.

Explain that flowers can only make seeds once pollination and fertilisation has happened.

This lesson could be enriched by taking pupils to an outdoor space with a few different types of flowering plants and giving them the opportunity to identify the parts on flowers that look very different to each other.
