The Breathing Process of Trees 0 13

Yes, it occurs in two ways.

Trees, like all plants, exchange gases in two opposite directions. During photosynthesis, they absorb carbon dioxide and release oxygen. At the same time, a process similar to animal respiration occurs: the absorption of oxygen and the release of carbon dioxide.

During the daytime, photosynthesis actively takes place in the green parts of the plant, so the tree primarily “inhales” carbon dioxide and “exhales” oxygen. At night, photosynthesis stops, and the tree begins to absorb oxygen and release carbon dioxide. The tissues of the non-green parts of the tree are incapable of photosynthesis, so they breathe oxygen around the clock. Oxygen enters the roots from the soil, and into the trunk tissues through cracks in the bark and with sap from the leaves.
