An Investigation to determine the Water potential of Potato cells Baldeep Bains Hypothesis and background information The cells that are to be used in this investigation will be of a white potato; parenchyma cells. These cells are large, thin-walled and usually have a large vacuole, which holds water, and are filled with sap, 'a solution of ions, sugars and enzymes capable of digesting proteins'. These substances are the solutes that will affect the water potential of the potato cells. Food storage in the form of starch grains is the main function of potato tuber cells. The plasma membrane that bounds a cell is partially permeable; it allows only small molecules such as water, to pass through. Potato cells also have cell walls; these have a rigid lattice structure but are freely permeable.
