The purpose of this experiment is to test the tonicity of potato cells. The potato cells are placed in six different Sucrose concentrations and left for an hour. The percent change in mass is then used to determine if the cells lost or gained water, therefore determining tonicity of the cell. The results show that the higher the concentration of sucrose the potatoes were placed in, the more hypotonic the potato becomes. INTRO It was hypothesized that as the potatoes were placed in higher amounts of sucrose concentration, they would have a negative percent change in mass, meaning they would lose more water. The null hypothesis states that as the potatoes are added to increasing amounts of sucrose solution, the percent change in mass would not change at all. Starting with strips of raw potatoes, cut approximately 4 cm in length using a razor blade, these strips are separated into six groups of approximately equal mass. An empty weigh boat is then weighed on the balance to determine the starting weight before the potatoes are added. Weight each individual pile of potatoes separately until all six
