Gases such as oxygen and carbon dioxide cross the plasma membrane by

Diffusion - the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration.This is because these molecules are non-polar and can easily travel across the hydrophobic parts of the plasma membrane :) Hope this helped you! Have a wonderful day!
