Osmosis is the movement of water from an area of high concentration to an area of low concentration across a semi permeable membrane. An osmotic system is established when a semi-permeable membrane is placed between two solutions. In this biological systems context‚ osmosis is the exchange of water between the potato cell and the surrounding medium of varying sucrose concentrated solutions‚ with the plasma membrane being the semi- permeable membrane. Because water molecules have kinetic energy‚ they
