Question

How do substances like co² and water move in and out to the cell

Answer 1

Substances like CO2 and water move in and out of a cell by a process called diffusion, which takes place from a region of high concentration of solute to a region of low concentration of solute. When the concentration of CO2 and water are higher in the external environment than that inside the cell, CO2 and water move inside the cell. When the concentration of the solute outside the cell becomes low and it is high inside the cell, the movement happens outwards.
