Investigate the different water potentials of a fruit and a vegetable. Objective: The objective of this experiment is to determine the water potential of both apple cells and potato cells and to see how they differ from one another. We will do this by placing the apple and potato chips in different molarity solutions for a period of time and recording the changes in mass. Hypothesis: The theory for this investigation, which is to be proved or disproved, is that as the molarity of the solution increases the average percentage difference in mass will decrease of both the apple and the potato cells. This means in a lower molarity the chips may increase in mass slightly but in a higher molarity the mass of the chips will decrease. Background information: The whole idea of the investigation revolves around the theory of osmosis. The definition of this term, is "the movement of water molecules from an...
