Detailed explanation-2: -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: -The plasma membrane is the common boundary between the cell and its environment in all cells. It is the outermost covering of animal cells. It is the elastic and semipermeable membrane and regulates what enters and exits the cell. The cell wall forms the outermost boundary of plant cells.

Detailed explanation-4: -The cell membrane or plasma membrane is the boundary between a cell and its environment. All cells are surrounded by a structure called the cell membrane.

Detailed explanation-5: -The plasma membrane is the boundary of the cell, made up of lipids and proteins, and controls the substances entering or leaving the cell.
