explains that we need to Obtain a 5 cm piece of dialysis tubing. Clamp one end of tubing. Fill the tube with sugar/starch solution, clamp the other end. This is your “cell”.Weigh cell and record weight. Place your cell in beaker of 100% water. Wait 1 hour. After, Re weigh your cell and record weight.   Test water in beaker for the presence of sugar and for presence of starch using the standards procedure from Lab 2.   Initial weight
