How does a tree trunk exchange gases with the environment although it lacks stomata?

(N/A) In woody plants,the bark is covered by a layer of cork which is impermeable to gases.
To facilitate gas exchange,small pores called $Lenticels$ are present on the surface of the bark.
These $Lenticels$ allow for the diffusion of oxygen and carbon dioxide between the internal tissues and the external environment.
Additionally,they also facilitate a small amount of transpiration.
