Step-by-step explanation:
Plants release oxygen into the air through a cool process called photosynthesis. They use sunlight, chlorophyll (a green pigment), and water to turn carbon dioxide into glucose (a type of sugar) and oxygen. It's like a plant superpower! The oxygen they make gets released into the environment through tiny openings called stomata on their leaves. So, plants not only make food for themselves, but also give us the fresh oxygen we need to breathe.
