Answer :

Final answer:

Cell membranes play a vital role in separating cells from their environment, regulating material passage, and enabling cell signaling.


Explanation:

Cell membranes are crucial structures that separate a cell from its environment and regulate the passage of materials in and out of the cell. The pliable structure of cell membranes, primarily composed of back-to-back phospholipids and embedded proteins, allows for selective permeability and transport, as well as cell signaling.
