The common term for the process of osmosis in cells refers to the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This passive transport process is crucial for maintaining proper cellular function and homeostasis. By regulating water levels, osmosis ensures that cells do not become dehydrated or overly swollen. It plays a significant role in various physiological processes, including nutrient absorption and waste elimination, highlighting its importance in biological systems.
