Osmosis - MOVEMENT OF WATER MOLECULES ACROSS A PARTICALLY PERMABLE MEMBRANE FROM AN AREA OF HIGH CONCENTRATION TO A AREA OF LOW CONCENTRATION

- Only tiny molecules like water can pass through, large molecules like sucrose can't

- Water can pass both ways as it moves about randomly

- Osmosis is a type of diffusion, just with water instead

- Experiment to prove this is using potato cylinders
