Detailed explanation-1: -Cell Membrane (Plasma Membrane) 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.
Detailed explanation-2: -The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
Detailed explanation-3: -The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.
Detailed explanation-4: -The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.
