Answer: The movement of water from a region of high concentration of water to a region of lower concentration of water through a semi-permeable membrane.
Compare and contrast diffusion, facilitated diffusion and active transport.
Answer: Diffusion only works down a concentration gradient; facilitated diffusion takes place across membranes at specific carrier sites but only down a concentration gradient; active transport takes place across membranes at specific carrier sites but works against a concentration gradient and requires energy in the form of ATP (click on the diagram to see an animation).
