Define ‘diffusion’
Diffusion is the passive movement of particles from a region of higher concentration to a region of lower concentration, as a result of the random motion of particles.
Define ‘Osmosis’
Osmosis is the passive movement of water molecules from a region of lower solute concentration to a region of higher solute concentration, across a partially permeable membrane.
Define ‘active transport’
Active transport is the movement of substances across membranes using energy from ATP.
