Plants and trees are all around us. They are the grass you run on and the trees that are towering above you. Trees are large plants that have a long life cycle. That’s why they are so big. The parts of trees are roots, the trunk, branches, and leaves. The leaves take in carbon dioxide and sunlight. The roots suck up water and nutrients. That is then turned into sugar and oxygen that the tree can feed on. Trees can make their own food. This is called photosynthesis. Plants are smaller versions of trees. They have the same life cycle but the life cycle takes less time. The parts of a plant are roots, stem, and leaves. They also use photosynthesis. Plants and trees are critical to our existence. They provide us with oxygen so that we can breathe. Trees and some plants give us shade on hot days. Trees and plants are very important and they help us survive.
