Define the term osmosis and give an example.

Answer: Osmosis is the movement of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration, tending to equalise the concentrations of the solutes. Osmosis is passive transport, meaning it does not require energy to be applied.

Examples of osmosis in daily life include plant cells soaking up water, skin soaking up water, and slugs reacting to salt.
