Purpose: Examine the role of the cell membrane in the cell by disrupting its function using temperature (Biology 107 Laboratory Manual 2014). This will improve the general understanding of optimal growing temperatures and the breakdown of the cell membrane Procedure: Betacyanin solution of a known concentration was diluted to create a dilution series‚ then placed in a spectrophotometer set to 525 nm. The absorbance of the dilution was used to create a standard curve for betacyanin. Discs of living

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
