Question

What is the primary role of the bacterial cytoplasmic (plasma) membrane?
Options
A To synthesize proteins and ribosomes
B To provide rigidity and shape to the cell
C To act as a selectively permeable barrier, controlling transport in and out of the cell
Correct Answer
D To store genetic material (DNA)
Correct Answer

Option C is the correct answer.

Detailed Explanation

The cytoplasmic membrane is a phospholipid bilayer that lies just inside the cell wall. Its key function is selective permeability, meaning it controls which substances can enter and exit the cell. It also houses electron transport chain components for ATP production.

Hint

Think about what separates the cell's interior from its external environment and regulates molecular traffic.
