We all know that plants produce oxygen for us to breath but do they really need Oxygen? The short answer is yes. They need it for cellular respiration just like we do. While photosynthesis creates the majority of the energy a plant needs, they have mitochondria like we do and that requires oxygen as part of the citric acid chain. this is a minor but still critical, especially in those months where they can’t be green and soaking in the sun to photosynthesize
Key Takeaways:
- Plants need oxygen to survive because they respire too, which is kind of like reverse photosynthesis.
- While animals take in carbohydrates for respiration through food, plants have to make their own. This requires a good deal of energy, especially in the absence of light.
- While plants need oxygen to survive, growing plants create more oxygen than they consume overall. Therefore, all plant life on this earth is a major source of the planet’s oxygen.
“Under certain circumstances, plant cells need to take in more oxygen from the air than they generate themselves.”
