Patrick McCreanor BIOLOGY 4/12/02 Aim: To demonstrate the Water Potential of Potato Cells. Objectives: * To show the water potential of potato cells using various measured concentrations of a sucrose solution and pieces of potato. * To record and analyse data to verify observed results. The method and procedure was carried out as per instruction sheet. Observations: The experiment shows that the lower the concentration of the sugar solution, in the Petri dish, the mass of the potato increased. This is because the water molecules passed from a high concentration in the water, to a low concentration, in the piece of potato. Therefore, the potato in higher water concentrations will have a larger mass than in higher sucrose concentrations. i.e. The potato pieces are shown to have water potential. The attached graph shows the concentration of the sucrose solution plotted against the average mean change in mass. At point A the graph shows that no change in mass, of the...
