HEYA,
Leaves. The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

in roots the exchange of gases takes place by the process of diffusion from the air present between the soil particals, oxygen diffuses into the root hair and passes through the root cell from where the carbon dioxide moves out into the soil
IN STEM
in woody plants, gaseous exchange occurs through the small pores in the stem called lenticels ,on other hand for herbaceous plants stomata on the stem aid in the respiratory process
