Beetroot Practical 2.8 An investigation to find out whether the raise of temperature will increase the permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim
