Investigating to see what effect temperature has on the permeability of the beetroot cell membrane. Hypothesis I predict that as you increase the temperature of the water the test tube containing the beetroot is placed in, the more permeable the cell membrane will become. This is due to an increase in kinetic energy meaning the particles will have more sufficient energy to move around at a faster rate increasing the rate of reaction. Thus more pigment will leave the cell membrane. I also predict that when the temperature rises above optimum, the proteins within the cell membrane will become denatured leaving gaps in the cell membrane, therefore allowing more pigment to leave cell membrane. Absorbency (A) Temperature (°C) Apparatus In my investigation I will be using the following equipment: * Beetroot * Size 4 cork borer: so that all the beetroots are same size, as I will not be testing to see what effect the...
