An investigation to show how different temperatures of water and concentrations of alcohol affect membrane permeability Aim The aim of the experiment is to show the cell's membrane permeability is affected by being placed into different temperatures of water. Also the effect of placing beetroot in to different concentrations of alcohol. Beetroot cells contain a red sap, which leaks out of the cells if their membranes are damaged or altered. Cell membranes are made up of a bilayer of phospholipids, which also contains proteins. Which either float around or are fixed. Some are found in the inner or outer layer and some span the whole membrane Carbohydrate chains attach themselves to the external membrane forming glycoproteins and glycolipids. It also contains cholesterol. We will be able to tell how damaged they are because we will see a deeper coloured red in the water from where more of the red sap has leaked...
