The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. When the concentration of CO2 and water is higher in external environment than that inside the cell, CO2 and water moves inside the cell. When the concentration outside the cell becomes low and it is high inside the cell, they moves out.

[?] Carbon dioxide moves across the cell membrane by diffusion. When CO2 concentration in the cell increase in comparison of the CO2 concentration outside the cell there is spontaneous movement of CO2 from region of higher concentration to a region of its low concentration. [?] Water molecules move through selectively permeable plasma membrane by osmosis. Dissolved substance present in water affect the movement of water across plasma membrane.
