Detailed explanation-2: -Other names of cell membrane are Plasma membrane (PM), cytoplasmic membrane and plasmalemma.
Detailed explanation-3: -The four major classes of lipids in the plasma membrane are glycolipids, phospholipids, sphingolipids, and sterols.
Detailed explanation-4: -Why it is called a plasma membrane? The cell contains a protoplasm (or simply plasm), which is the semi-fluid living matter. This living matter or plasm is contained inside a biological membrane referred to as the plasma membrane.
