Plants are living things that are very important for our world. Most plants have four main parts: the roots, the stem, the leaves, and the flower. Each part has a special job. The roots grow under the ground. They take water from the soil and help the plant stay in one place. Above the ground is the stem. The stem gives support to the plant and carries water to the other parts. The leaves grow on the stem. They use sunlight to make food for the plant. This is a very important process. Many plants also have flowers. Flowers are often colorful and help the plant to make seeds. New plants can grow from these seeds. All these parts work together to help the plant live and grow.
