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.

Detailed explanation-2: -The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments. In the case of the plasma membrane, these compartments are the inside and the outside of the cell.

Detailed explanation-3: -Plasma membrane refers to the membrane that surrounds the organelles of the cell, by creating a barrier between cell organelles and the external environment. The plasma membrane is a thin membrane that surrounds every living cell, separating it from the external environment around it.

Detailed explanation-4: -Inside the cell there is a large fluid-filled space called the cytoplasm, sometimes called the cytosol. In prokaryotes, this space is relatively free of compartments. In eukaryotes, the cytosol is the “soup” within which all of the cell’s organelles reside. It is also the home of the cytoskeleton.

Detailed explanation-5: -The membrane separates cells from one another and also the cell from the surrounding medium.
