CAIE IGCSE Biology 3.2.4 Osmosis using materials such
Practise interpreting dialysis tubing investigations, including changes in liquid levels and evidence for osmosis over time.
How this is tested
- predict the movement of liquid in glass tubes in a dialysis tubing osmosis setup
- use apparatus diagrams to link membrane permeability with net water movement
