Plants are living things that make our Earth green. There are many different kinds of plants, and they come in all shapes and sizes. Plants can be small like mosses, or very large like trees. Some plants grow in the ground, while others grow on trees or rocks.
Plants need sunlight, water, and air to live. They use sunlight to make food from carbon dioxide and water. This food is called glucose, and it is what plants use to grow and stay alive. Plants also give off oxygen gas as a waste product.
