Solution

Cell wall Cell membrane
The cell wall is thin and permeable. It allows the movement of water molecules and dissolved substances freely in and out of the cell. The cell membrane is very thin, and semi-permeable, which means that it allows water molecules to pass through, but not the larger molecules of the dissolved salts.
