Cell Wall. Done with your homework yet?
For most cells, it is the cell membrane. Cells have a plasma membrane that is very selectively permeable i.e, will allow entry of substances that are necessary for the cell functioning. In case of an egg cell, it is surrounded by follicular cells. It provides protection from various acidic conditions. For a plant cell, the cell wall serves as a barrier.

Yes, the cell wall is entirely separated from the plasma membrane in both plants and bacteria. In plants, the cell wall is composed of cellulose and other polysaccharides and provides support and protection. In bacteria, the cell wall is made up of peptidoglycan and serves as a protective barrier.
