By the end of this chapter you will be able to

  • Put the stages of a flowering plant's life cycle in order, from a seed back to a seed
  • Say what pollination is, and how insects and the wind carry pollen from flower to flower
  • Explain how seeds form inside a fruit after pollination, and name a bean plant's fruit
  • Name four ways that seeds are dispersed, and say why spreading seeds helps a plant
  • Say what a seed needs in order to germinate, and read a table from a fair test on germination
  • Describe a seedling, and use a table to show how it grows

You should already know

  • Parts of a flowering plant: roots, stem, leaves and flower (Year 3 Science, Chapter 2)
  • What plants need to grow, and why crowded plants share light and water (Year 3 Science, Chapter 3)

Where this leads

  • Food and nutrition, and why animals must eat food that they cannot make themselves (Year 3 Science, Chapter 5)
  • Living things and their habitats, and how plants and animals depend on each other (Year 4 Science)
