How does alcohol concentration affect permeability of beetroot cell

WebTemperature, pH and concentration of alcohol are 3 factors that affect the membrane permeability of any cell. In the beetroot plant, the red or purple pigment that is located in the vacuole, which is embedded to the membrane, is called bectacyanin or betalain. Betalains are soluble in water, therefore it remains in the vacuole if its healthy. Webof an alcohol molecule is the nonpolar hydrocarbon segment. In solution, the hydrophobic part of an alcohol will inevitably interact with the polar heads of the phospholipids. The bigger the hydrophobic part, the more damage it causes. The alcohol solutions used in this experiment are clear and colorless. If beet membranes are damaged, earth focus geology
