Slowly, leaves come out on the stem. They are like little factories. The leaves collect sunlight and CO₂ during the day, and they mix them with water from the root. (A) They will produce sugar for the plant and oxygen for us. Plants give us more than food and oxygen. They are also useful for our health. When we feel tired, we can take a rest in a green park. Trees can make us happy. Plants are so important to us and to all the animals on the earth. Without them, we could not live.
