Osmosis
diffusion of water across a selectively permeable membrane
Osmosis is the movement of water molecules across a semi-permeable membrane from a region of high concentration to an area of low concentration until equilibrium is reached. This process is driven by the tendency of water molecules to move from an area of high concentration (low solute concentration) to an area of low concentration (high solute concentration).
In biological systems, osmosis is a critical process that helps regulate the movement of water and solutes into and out of cells. Cells are surrounded by a semi-permeable membrane that allows some molecules to pass through while preventing others from doing so. Water is a molecule that can easily pass through the membrane via osmosis, which helps maintain fluid balance across the cell membrane.
Many biological processes rely on osmosis, including the transport of nutrients and waste products between cells and the environment. If the concentration of solutes in a cell becomes too high, water will move out of the cell, leading to cell shrinkage and potential damage. On the other hand, if solute concentration outside of the cell is too high, water will enter the cell, leading to swelling and possible rupture.
Overall, osmosis is a critical biological process that helps maintain proper fluid balance and regulates the movement of nutrients and wastes in and out of cells.
