An investigation to examine the effects of temperature on membrane stability in beetroot, by assessing the degree of pigment leakage. Aim: - to discover how temperature affects the stability of the cell membrane in beetroot. Introduction:- Plant cells contain a plant cell wall as well as a cell membrane, which surround the protoplast (everything that is within the cell) of the cells. All cell membranes consist of a phospholipids bilayer, which are made up of two layers of phospholipids, hence the name. The plasma membrane is a partially permeable barrier between the cell and the extra cellular environment. The plasma membrane mainly consists of phospholipids. These phospholipids are a phosphate head, which is attached to two fatty acid tails (hydrocarbon chain). The phosphate group is highly soluble in water and so hydrophilic; however, the fatty acid tails are not soluble in water and therefore are hydrophobic. In the plasma membrane, the phospholipids...
