Answer 2

Answer:

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.
