Just like humans, plants need to breathe to survive. However, they do not have noses or lungs. Instead, they breathe through tiny openings called stomata. Stomata are mostly found on the undersides of leaves. They are so small that you can only see them with a microscope. During the day, plants take in carbon dioxide from the air through these stomata. They use this gas, along with sunlight and water, to make food in a process called photosynthesis. While making food, plants produce oxygen, which they release back into the air. At night, when there is no sunlight, photosynthesis stops. Plants then breathe in oxygen and release carbon dioxide, just like we do. This natural cycle is very important because it helps keep the air clean and provides oxygen for humans and animals to breathe.
