参考答案: Osmosis is the movement of water molecules.
Water molecules move from a hypotonic solution to a hypertonic solution.
The membrane is needed to separate the two solutions with different solute concentrations.
If the membrane is impermeable to the solute this prevents it crossing the membrane.
Note: Students should use the terms “hypertonic”, “hypotonic” and “isotonic” in D2.3
