Osmosis is the process of movement of water molecules from its

Osmosis is a specific type of diffusion involving the net movement of water molecules across a selectively or semi-permeable membrane. This process occurs from a region of higher water concentration (a dilute solution) to a region of lower water concentration (a concentrated solution). While water molecules move in both directions across the membrane, the net flow is driven by the concentration gradient until equilibrium is reached. A semi-permeable membrane is essential as it allows the solvent (water) to pass through while restricting the movement of larger solute particles [2]. This movement is vital for biological functions, such as maintaining cell turgidity in plants and regulating intracellular volume in animal cells. Therefore, osmosis is defined by the movement of water from its higher concentration to its lower concentration through a semi-permeable membrane.
