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 a lipid bilayer that surrounds the cytoplasm of a prokaryotic cell. It physically separates the cytoplasm from the outside environment. The plasma membrane also works as a selectively permeable, or semipermeable, barrier that controls what enters and exits the cell.

Detailed explanation-3: -The plasma membrane Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment.

Detailed explanation-4: -The plasma membrane (cell membrane) forms a barrier between the cytoplasm inside the cell and the environment outside the cell. It protects and supports the cell and also controls everything that enters and leaves the cell.

Detailed explanation-5: -Nuclear pores, small channels that span the nuclear envelope, let substances enter and exit the nucleus. Each pore is lined by a set of proteins, called the nuclear pore complex, that control what molecules can go in or out.
