Plants need to take in water and carbon dioxide as well as minerals and other nutrients.

In this topic you need to know about the following: -

  • What happens in diffusion, osmosis and active transport.
  • How we can demonstrate diffusion, osmosis and active transport through experiments.
  • How water and sugars are transported around the plant.
  • How the stomata limits water loss in a plant.
  • How we can use potometers to measure water movement in a plant.

    • Use the arrows below to continue to revise.
