  • Hypothesis: to investigate the effect of different concentrations of ethanol on the permeability of beetroot cell membranes prediction: by exposing a membrane to a solvent, ethanol, it will increase its permeability so the higher the concentration of the solvent, the more permeable the membrane.

The location of the ethanol creates a strong hydrogen bond between the water moleculesif the solute concentration outside the cell is greater than inside the cell,ethanol which is a (non–polar / organic) solvent,enters the membrane and since lipids dissolve (in alcohol) increase in ethanol causes solution to be less polar leading to.
