GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The plasma membrane is selectively permeable; it regulates what passes from one side to the other. A selectively permeable membrane will allow water to flow freely while limiting the passage of molecules, especially large molecules or those with a charge.

Detailed explanation-3: -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-4: -The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.
