Sucrose (C12 H22 O11) is formed by a condensation reaction between Fructose and Glucose. POTATOES Potatoes are natural forms of carbohydrate, which are rich in starch. OSMOSIS Osmosis is the movement of a solvent (usually water in biological systems) through a differentially permeable membrane from a solution that has a high water concentration to one with a low water concentration and high solute concentration. Diagram 1: osmosis. WATER POTENTIAL Water potential is the tendency of a cell to draw in water from outside by osmosis with the water moving from a higher to a lower potential. Since pure water at one atmosphere has a water potential of zero, cells drawing in water have a water...
