Detailed explanation-1: -Cell Membrane (Plasma Membrane)
Detailed explanation-2: -The plasma membrane is the border between the interior and exterior of a cell. As such, it controls passage of various molecules-including sugars, amino acids, ions, and water-into and out of the cell.
Detailed explanation-3: -The Cellular Membrane The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.
Detailed explanation-4: -Plasma membranes enclose the borders of cells, but rather than being a static bag, they are dynamic and constantly in flux. The plasma membrane must be sufficiently flexible to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries.
