Cellular transport

**Cellular transport** refers to the various mechanisms cells use to move substances across their membranes. This essential biological process enables the intake of nutrients, removal of waste, and communication between cells. Cellular transport includes passive methods like diffusion and osmosis, as well as active processes such as endocytosis, exocytosis, and active transport, which require energy. Understanding cellular transport is crucial for studying cell function, physiology, and the basis of many medical conditions.
