An investigation into how the the temperature affect the permeability of cell membrane Aim: This experiment aims to determine what effect with an increase in the surrounding temperature has on the plasma membrane of a beetroot cell structure. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of a cell. The membrane is an extremely thin layer (8 to 10 manometers (nm)) thick, which is partially permeable. It consists mostly of lipids and proteins. The lipids found in cell membranes are phospholipids because they have one molecule of glycerol chemically linked to two molecules of fatty acids and a phosphate group. Despite there are many differences in appearance and function, all cells have a surrounding membrane (called the plasma membrane) enclosing a water-rich substance called the cytoplasm. All cells have a variety of chemical reactions that enable them to grow, produce...
