ACTIVE TRANSPORT Exocytosis Endocytosis Definition: Large molecules (waste) leave the cell by a vesicle. DOES NOT use energy! Definition: Large molecules (food) enter a cell by a vesicle. USES ENERGY!
PASSIVE TRANSPORT Diffusion • Osmosis Definition: The movement of particles from an area of high concentration to an area of low concentration. DOES NOT use energy! Definition: A special kind of diffusion that describes the movement of water through the membrane. USES ENERGY!
