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

Explanation

The substance like `CO_(2)` and water move in and out of a cell by diffusion from the region of high concentration to low concentration. When the concentration of `CO_(2)` and water is higher in external environment than inside the cell, `CO_(2)` and water moves inside the cell. When the concentration outside the cell becomes low and it is high inside the cell, they moves out.
