The structure of the cell membrane the cell membrane (or op) of the solution that surrounds a cell will affect the state of the cell, due to osmosis. Osmosis takes place in all cells the cell membrane is partially permeable osmosis in red blood cells if a red blood cell is placed in water, water enters the cell by osmosis because the membrane is quite weak the cell will burst as the volume and therefore the pressure in the cell increases red.
