Detailed explanation-1: -The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
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 plasma membrane protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.
Detailed explanation-4: -The main function of 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-5: -Solution : Plasma membrane regulates the exchange of materials between cytoplasm and extracellular fluid. Cell wall provides shape as well as rigidity to the cell.
