Question

A beetroot slice is first washed and then placed in cold water and it does not lose its anthocyanin. This shows that the plasma membrane is

• A. Impermeable to anthocyanin
• B. Permeable to anthocyanin
• C. Differentially permeable to anthocyanin
• D. Dead

Answer 1

The correct option is A Impermeable to anthocyanin

Anthocyanin is the red coloured pigment which is present in the beetroot. The pigment is produced inside the cell. The plasma membrane is impermeable and does not allow the pigment to leak out. The slices were washed and placed in cold water which does not destroy the plasma membrane and so, the pigment does not gets released.

Thus, the correct answer is option A.
