Transport in cells is a fundamental process that ensures the movement of substances necessary for cellular function. This includes the transport of ions, nutrients, and waste products across the cell membrane. Cells utilize various mechanisms to facilitate this process, such as passive transport, which relies on diffusion and osmosis to move substances along their concentration gradients, and active transport, which uses energy to move molecules against their gradients. Additionally, cells use vesicular transport, including endocytosis and exocytosis, to move large molecules and particles. Efficient transport systems are crucial for maintaining homeostasis and supporting cellular activities .
