The outer layer of woody stem has small holes called lenticels which perform exchange of gases.
Lenticels are raised surface on the bark made up of porous tissues composed of cells with large inter-cellular spaces. These cells have large inter-cellular spaces so that they can exchange gases between the plant and the environment.
