Detailed explanation-1: -The main function of the plasma membrane is that it acts as a physical barrier between the external environment and the inner cell organelles. The plasma membrane is a selectively permeable membrane, which permits the movement of only certain molecules both in and out of the cell.

Detailed explanation-2: -The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Detailed explanation-3: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-4: -The plasma membrane protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.

Detailed explanation-5: -Just as the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.
