Investigate the Effect of Temperature Change on the Permeability of Beetroot Cell Membrane.

... Investigate the Effect of Temperature Change on the Permeability of Beetroot Cell Membrane. Aim In this investigation I will examine whether there is a relationship between the amounts of leakage of beetroot pigment into water under various range of temperatures. Furthermore, I will also investigate if there is a correlation between absorbency and temperature. Hypothesis With high temperatures it is likely that the phospholipids in a Beetroot Cell Membrane will move faster. This will inevitably result in the membrane becoming for permeable. Therefore, I predict that, there will be a positive relationship between permeability and temperature. I also predict that there will be a positive correlation between the two variables, which means as the temperature increases the absorbency will inevitably increase. Null Hypothesis There will be no relationship between the rise in temperature and the amount of beetroot pigment leaking into the water.
