Practice Question

Which is NOT a characteristic of the plasma membrane?

Answer Choices:

Correct Answer:

Maintains cell shape

Rationale:

» The plasma membrane is primarily responsible for selective permeability, which means it controls the substances entering and leaving the cell.

» It is also composed of a phospholipid bilayer with embedded proteins, which participate in transport, signaling, and structural support.

» Some antibiotics target the plasma membrane, making it a key site for antimicrobial action.

» Maintaining cell shape is the role of the cell wall in bacteria or the cytoskeleton in eukaryotes, not the plasma membrane, which is why “maintains cell shape” is not correct.
