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

Text Solution

Verified by Experts

The old tree trunk is covered by dead woody tissue called cork. The epidermal layers of such tree get ruptured and outer cortical cells are loosely arranged . These structures are called as lenticels.
These are the sites of gases exchange and transpiration
