Do trees need to breathe?

Like all animals and humans, trees also need to breathe because breathing can provide them with the energy they need for growth. Although trees do not have long nostrils, they have breathing pores. If you use a magnifying glass to carefully examine their leaves, there are really many small holes on them! Oxygen, carbon dioxide, and other gases enter and exit through these small holes. These small holes, also known as stomata, are usually distributed on an ordinary leaf with approximately 500000 stomata. In addition to stomata, some plants also have many linear or circular spots on their branches and stems, called pores, which are also the respiratory organs of plants. The small holes on the trunk are like human nostrils, never closed, so the trees, like us, breathe fresh air all the time, day or night.

Most of the respiration processes in plants require the participation of oxygen, which is called aerobic respiration. Aerobic respiration is the main mode of plant respiration.
