Explanation:

The process by which oxygen and carbon dioxide move in and out of the cell is called diffusion.
Diffusion is the process by which gas or liquid particles move to reach equilibrium or to become equally distributed throughout the space available in the cell. There is net movement from area of high concentration to low concentration. Also diffusion does not required the input of energy. It does this passively.
