Aim To investigate the effect of varying sucrose (sugar) concentration on potato cells and to find out the concentration of sucrose in the potato cells. Back round info Osmosis is defined as 'the movement of water molecules from an area of high water concentration to an area of low water concentration, across a semi-permeable membrane. In a high concentration of water the amount of solute (sugar) is low. This is called a dilute solution. In a low concentration of water the amount of solute (sugar) is high. This could be called a concentrated solution. When two such solutions are divided by a semi-permeable membrane. The water will move from the area of high concentration to the area of low concentration, until both sides are equal or have reached equilibrium. This can be seen in living cells. The cell membrane in cells is semi-permeable and the vacuole contains a sugar/salt solution. Factors and fair...
