Quizplus · Accepted Answer

Diffusion is the movement of a substance from an area of higher concentration to an area of lower concentration. This process does not require energy, unlike active transport where substances move against a concentration gradient and use energy, or metabolism where substances undergo chemical reactions within the body. Osmosis is the movement of water across a semi-permeable membrane from an area of higher concentration to lower concentration of solutes, and is a specific type of diffusion.
