How does concentration affect osmosis? Rajwinder Mandair April 07 Introduction Osmosis is the diffusion of water molecules that occurs only when there is a movement of water molecules from a region of higher concentration to a region of lower concentration through a partially permeable membrane. The process ends only when the two concentrations are equal or the cell is unable to take any more water because the cell is turgid. For osmosis to take place a partially permeable membrane is required to allow water movement to take place and to prevent such a transfer between other molecules. If a cell is in contact with a solution of lower water concentration than its own contents, then water leaves the cell by osmosis, through the cell membrane. The living contents of the cell contracts and eventually pulls away from the cell wall and shrinks, this is known as plasmolysis. If you put...
