Detailed explanation-1: -A cell membrane or plasma membrane is a thin, delicate membrane surrounding the cytoplasm. The following are the functions of the cell membrane: It separates the cells from one another and also separates the cells from the surrounding medium. It gives a definite shape to the cell.

Detailed explanation-2: -Definition. 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-3: -What Are Cellular Membranes Made Of? With few exceptions, cellular membranes-including plasma membranes and internal membranes-are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.

Detailed explanation-4: -The cell membrane is located on the cell walls of the cells in animals. The cell membrane is situated between the cytoplasm and cell wall in plants.
