Question

Choose the correct answer from the alternatives given.
The major functions of the plasma membrane do not include

• A. Separation of the fluid environments inside and outside the cell
• B. Regulation of molecules and ions that pass into and out of the cell
• C. Recognition and communication between different cells and tissues
• D. Production of proteins used in construction of the cell wall.

Answer 1

Answer: (D)

Production of proteins used in construction of the cell wall.

The plasma membrane of a cell is a semipermeable membrane that protects the inner contents of the cell by separating the inner environment of the cell from the outer environment. It also maintains an electrochemical gradient between the inside and outside of the cell. It is composed of phospholipid bilayer which has integral and peripheral proteins embedded in it. However, it is not involved in the production of proteins used in the construction of the cell wall.

So, the correct answer is 'Production of proteins used in the construction of the cell wall'.
