Aim How temperature affects membranes: investigating the effect temperature has on Beta vulgaris membranes when submerged in a range of different temperatures for one minute. Background Information A cell membrane is made up of a phospholipid bilayer formed by phospholipids that have a hydrophilic head and a hydrophobic tail. The phospholipids arrange themselves in order that the heads are exposed to water and the tails are not thus forming the bilayer. When the temperature increases molecules
