Determine the Water Potential of Potato tissue The aim of this experiment is to determine the water potential of potato tissue, using different concentrations of sucrose solution. If plant cells are placed in pure water, water will initially move into the cells. After a period of time the cells will become turgid. Turgor pressure is the pressure exerted against the cell wall by contents of the cell. At first most water movement is into the cell. As the turgor pressure increases water will begin to diffuse out of the cell at a greater rate, eventually equilibrium will be reached and water will enter and leave the cell at the same rate. This stage is used to find the water potential of a particular cell. Potato cells contain polysaccharides starch and glycogen they are good for storage. The potato cell is surrounded by plasma membrane it is a fluid mosaic model, which is a...
