Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The
