Cytoplasmic membrane barrier that separates the inside of the cell from the outside environment . Cytoplasm aqueous mixture of macromolecules, ions, and proteins . Plasma membrane is used to make atp and a barrier to allow the proton concentration to increase to couple for atp production for the prokaryote. Fluid and everything else that is within the boundaries. Cytoplasm = cells are made of 60 80% water .
