Perhaps you have heard of trees being referred to as the “Lungs of the World?”
Trees, like all green plants, rely on photosynthesis for their nutrition.
Photosynthesis happens in the chloroplasts of the plant cells. The process is driven by the light every from the sun. The leaves absorb carbon dioxide from the atmosphere through tiny holes in the leaves, called stomata, and use the light energy to carry out a chemical reaction with water from the soil to produce glucose. The waste product of this reaction is oxygen, which the plant allows to leave through the stomata of the leaves.
So, not only do trees take in carbon dioxide, removing it from the atmosphere, but they also produce oxygen, the gas that is vital for life on Earth. The more trees, the easier the fight against carbon dioxide, climate change and global warming.
Until next time, keep calm and apply some Science!
