An experiment to test the effect of different temperatures on the permeability of cell membrane. Aim In this experiment, I am trying to find out how, why, and by how much does the difference in temperature affects the permeability of cell membrane of plant cells. Prediction Having done a pilot experiment and by using the scientific knowledge gathered, some predictions can be made. The permeability of cell membrane should increase as the temperature increases, and this is shown by the decrease in the percentage transmission of light on the colorimeter. As guidance, the results of the pilot experiment could be used: Theory of prediction There are five possible ways that the dye could leak out of the cell in normal condition without the aiding of heat, and these are simple diffusion through the lipid bi-layer, facilitated diffusion by protein carriers, and facilitated diffusion via ion channels, active transport, and exocytosis. * The dye would have...
