The Cytoplasmic Membrane Could Best Be Described As

Question

The cytoplasmic membrane could best be described as
A) an impermeable barrier.
B) a passive conduit for intracellular transport.
C) a highly selective permeability barrier.
D) a rigid structure that protects the cell.

Accepted Answer

The cytoplasmic membrane is a highly selective permeability barrier that only allows specific molecules to pass through while preventing the entrance of others. It regulates the movement of ions and nutrients into and out of the cell, maintains the cell's shape and integrity, and plays a crucial role in cellular communication and signaling.
