An experiment to investigate how temperature affects the Permeability of beetroot cell membranes Interpretation of Results: 0°C 20°C 30°C 40°C 55°C 0.24 0.28 0.75 0.79 0.22 0.26 0.35 0.41 0.81 From 0°C to 30°C there is a gradual increase of absorbency which shows that as the temperature increases it is denaturing the cell wall and cell membrane and allowing the beetroot pigment to leek out into the distilled water. As soon as the sample of beetroot is placed into the distilled water diffusion occurs naturally, which is the net movement of molecules from a region of high concentration (beetroot sample) to a region of low concentration (distilled water). From 40°C upwards there is a sudden increase of absorbency, this is because the optimum temperature of which enzymes and cells can work at is 37°C and as soon as you go above this temperature it will cause the enzymes and cells to denature and cease from working as effectively. Even if you then lower the temperature again the...
