Diffusion, Osmosis, Active Transport
Osmosis Osmosis is a special example of diffusion. It is the diffusion of water through a partially permeable membrane from a more dilute solution to a more concentrated solution – down the water potential gradient) Note: diffusion and osmosis are both passive, i.e. energy from ATP is not used.
