How do substances like CO 2 and water move in and out of the cell?

Diffusion is the movement of solute molecules from a region of higher concentration to the region of lower concentration. Carbon dioxide is transported in an out of the cell by the process of diffusion. In contrast, osmosis is the process in which the movement of solvent molecules takes place from the region of higher concentration to the region of lower concentration in the presence of a semi-permeable membrane. Water is transported in and out of the cell by osmosis.
