The permeability of a cell membrane is affected by the polarity, electric charge and molar mass of the molecules that diffuse through it. Practical assessmentplanningaimbeetroot cells contain a red pigment, which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell.
Extracts from this document introduction how does temperature affect the permeability of a cell membrane in a beetroot introduction: the purpose of the cell membrane is to control the transport of substances moving into and out of the cell. Ethanol is a non polar solvent, and the phospholipid bilayer of the beetroot cell membrane is also non polar non polar solutes dissolve in non polar solvents, and lipids dissolve in alcohol (ethanol is an organic solvent that can dissolve non pol. Beetroot cells have been chosen for this activity because each beetroot cell has a large central vacuole bounded the cell membrane is the same in both plants.
