Investigating the effect of Temperature on the Cell Membrane of Beetroot Cells Aim To investigate what effect temperature has on the integrity of the plasma cell surface membrane of beetroot cells. Background information Despite their many differences in appearance and function, all cells have a surrounding membrane (called the plasma membrane). The cell membrane of plant cells is an integral part of the cell as it controls the transport of substances needed by the cell such as water and molecules dissolved in the water (salts and glucose) both into and out of the cell. The actual membrane is a thin layer (8 to 10 manometers in width), which is partially permeable. It is composed largely of lipids and proteins. Most of the lipids on the cell membranes are triglycerides (they have one molecule of glycerol chemically linked to three molecules of fatty acids) and the skin of the membrane is made of phospholipids....
