Prediction
Osmosis is the "net movement of water molecules from an area of high water potential to an area of low water potential through a partially permeable membrane." The diagram below illustrates the process of osmosis. (See Figure 1)
As shown by the Figure 1, water molecules move from a region where there are many water molecules to an area of less water molecules.
This means that in the potato cells, water molecules will move in or out of the cell depending on the concentration of the sucrose solution and the water potential that the cell has. The process of water molecules moving out a cell is called exosmosis and the process of water moving into a cell is called endosmosis. Endosmosis occurs when the water potential inside the cell is lower than the water potential outside the cell.
Figure 2 illustrates the processes that will occur in the cells.
As varying concentrations of sucrose solution will be used, ranging from 0.0M to 1.0M the amount of water molecules......
