The phenomenon of osmosis occurs when pure water flows from a dilute saline solution through a membrane into a higher concentrated saline solution. Figure 1.4 Overview of osmosis As a fundamental Overview. The plasma membrane is the boundary that separates the living cell from its . surroundings. It controls what goes in and what goes out.

Osmosis is the movement of water through a selectively permeable membrane. The water moves from an area of high concentration of water to an area of lower concentration of water. . Osmosis. The diffusion of water across a differentially permeable membrane has been given a special name it is called, Osmosis , Osmotic pressure develop on all side of the membrane that has the higher solute concentration.
