. Diffusion is the movement of substances from a region of high concentration to a region of low concentration across the membrane.

.Osmosis is the movement of water molecules from a hypotonic solution to a hypertonic solution across the membrane.

.Active transport is the movement of substances from a region of low concentration to a region of high concentration across the membrane with the utilization of energy.
