An experiment to test the effect of concentration of sugar solution on potato cells by Claire Jaeger 11k September 2002 Background information: Osmosis is the passage of solvent molecules from a dilute solution into a more concentrated solution, through a semi-permeable membrane. Osmosis continues across a membrane until the two solutions either side have reached the same concentration. We call this state equilibrium. Osmosis can be seen in living cells. The cell membrane in cells is semi- permeable and the vacuole contains a sugar solution. So when a cell is placed in distilled water, a high water concentration, water will move across the semi-permeable membrane into the cell, a lower water concentration, by osmosis. The cells swells until there is no space left. The cells increase in length, volume and mass because of the extra water but do not burst because of the cell wall. This cell is now referred to as turgid and...
