Vedclass · Answer

(A) The plasma membrane is a selectively permeable membrane that maintains the integrity of the cell contents. At room temperature (cold water),the membrane remains intact and prevents the leakage of pigments like anthocyanins from the cell. When the water is boiled,the high temperature causes the denaturation of proteins and the destruction of the lipid bilayer of the plasma membrane. This loss of semi-permeability allows the pigments to leak out into the surrounding water,causing the water to change colour.

Purple cabbage leaves do not lose their colour in cold water but do so in boiling water because:
