Vedclass · Answer

(A) The cell membrane is a selectively permeable membrane. Under normal conditions or when kept in cold water/ice,the membrane remains intact and maintains its selective permeability,preventing the leakage of large molecules like anthocyanin pigments from the vacuole. If the beetroot were boiled or treated with chemicals,the membrane would lose its integrity and become permeable,causing the pigment to leak out. Therefore,the lack of leakage indicates that the membrane remains impermeable to anthocyanin under these conditions.

When cylindrical pieces of beetroot are washed with cold water or ice,the anthocyanin pigment does not leak out. What does this indicate about the behavior of the cell membrane?
