My independent variable is going to be the concentration of the solution-how much sucrose and distilled water in each solution. In my experiment, I plan to find out whether the concentration of sugar in distilled water affects how much water will go into a potato chip. Osmosis: the movement of water molecules from an area of high concentration to an area of low concentration. Cell membranes are completely permeable to water; therefore, the environment the cell is exposed to can have a dramatic effect on the cell. When plant cells are placed in concentrated sugar solutions they lose water by osmosis and they become "flaccid"; this is the exact opposite of "turgid". If you put plant cells into concentrated sugar solutions and look at them under a microscope you would see that the contents of the cells have shrunk and pulled away from the cell wall:...
