Name the processes by which $CO_{2}$ and $H_{2}O$ move into and out of the cell.

(N/A) The movement of $CO_{2}$ into and out of the cell occurs through the process of diffusion,which is the spontaneous movement of a substance from a region of higher concentration to a region of lower concentration.
The movement of $H_{2}O$ into and out of the cell occurs through the process of osmosis,which is the movement of water molecules from a region of higher water potential to a region of lower water potential through a selectively permeable membrane.
