Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient. Paul Andersen starts with a brief description of diffusion and osmosis. He then describes the diffusion demonstration and how molecules move over time. He 2020-04-25 · Passive Transport Definition. Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.
