Workers there will collect sunlight and CO₂. Then they will mix water, CO₂ and sunlight together. After that, they will produce sugar for the plant to grow. They will also produce oxygen, but the plant doesn‘t need much. That oxygen is a gift to animals and humans – we need it to breathe! Without this “factory”, life on Earth would be very different. So let’s protect plants. They work hard for us every day. 1 学科网（北京）股份有限公司 $
