How do substances like CO2 and water move in and out of the cell?

Asked by Topperlearning User 29th April 2016, 2:14 PM
Answered by Expert

CO2 moves in and out of the cells by the process of diffusion which involves the movement of molecules from a region of higher concentration to a region of lower concentration across the cell membrane.

Water moves in and out of the cells by osmosis which involves the movement of water through a semi-permeable membrane from a solution of lower concentration of solutes to higher concentration of solutes to which the membrane is relatively impermeable.
