Plant roots are like the heart and brains of a human: They perform the functions necessary to sustain life. Roots anchor the plant into the ground, provide and store the food the plant needs to grow and to reproduce, give plants the water they require to survive, and take in necessary minerals, such as nitrogen and sulphur. Plants can’t move around the way animals do, so they can’t go out and search for food. Instead, plants employ some marvellous and ingenious methods to endure and propagate. Most plants have to make their own food. In a process called photosynthesis, plant leaves trap sunlight and use its energy to change carbon dioxide gas and water into a form of sugar called glucose. Glucose gives the plant energy and is used to make cellulose, which builds cell walls.
Plant leaves lose water by evaporation through tiny holes, or stomata. These microscopic openings also let carbon dioxide in and oxygen out. As the water is lost, more water is drawn up through the roots, in a process called transpiration.
