Investigating The Effect Of Temperature Change On The Permeability Of Beetroot Cells. Aim This investigation aims to determine how an increase in the surrounding temperature affects plasma membrane of a typical plant cell structure. Hypothesis Increasing the temperature above a certain extent will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction Beetroot has a red pigment (anthocyanin) stored within its cells; it is prevented from leaking out by its cell membrane. The membrane is an extremely thin layer (8 to 10 nanometers (nm)) thick which is partially permeable. As we know, cell membranes are made up of lipids and proteins, and proteins tend to be affected by temperature. This investigation intends upon finding out if temperature has any effects on the permeability of beetroot cells, my prediction is that it does. This is because when the temperature is...
