Movement of Sucrose Across Plant Cell Membranes

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 makin
