Cells complete essential activities of organisms, such as growth and repairing damaged areas, by consuming energy. In a single organism, cells often work together simultaneously. For example, when you are reading this article, not only your eye and brain cells are working, but also other cells in your body are at work. Your intestinal cells are digesting food, and blood cells are transporting compounds within the body. If you get injured at this time, some cells will come to "repair" this wound.
