The cell membrane is a barrier between the internal and external environments of a cell. Water molecules are the sole molecules that can freely move across the cell membrane. This process is known as osmosis, and it is stated as being the net movement of water across a cell membrane. For this study, we obtained potato tubers and immersed them in different solutions of sucrose concentrated water. The purpose of this study was to determine the osmotic concentration of potato tuber cells by their change in mass.

(Ha:) It was hypothesized that the final mass of the potatoes immersed in the solution of sucrose would change, due to the net movement of water. We also hypothesized that the mass of the potatoes immersed in the distilled water containing no sucrose would be greater. We came to this hypothesis by maki

Six potato tubers were obtained, each cut to 4 cm. All six cylinders were placed on a moistened paper towel, and each was removed to be thinly sliced with a razor blade. Each sliced potato tuber was rinsed and blotted dry, then placed in an empty weight boat to be weighed on the balance. The balance was tared before each tuber was weighed. After each tuber was weighed, the mass was recorded on a chart. Each tuber was placed in a solution of sucrose and water, each solution containing a higher solution of sucrose than the next. The first contained no sucrose, just distilled water. Each solution that followed contained a molarity of 0.1, 0.2, 0.3, 0.4, and 0.5 of the sucrose.

The results supported our hypothesis that the mass of the potato tubers would change, according to the sucrose solution it was immersed in. In the solution containing no sucrose, the tuber did gain mas
