In addition, the stem serves as a backbone, offering the plant support and structure. You can think of the stem as a passage way for water and food. The leaves produce food (glucose) which is also transported throughout the plant by the stem. Usually stems grow above ground and transport water and nutrients from the roots to the leaves and flower. For some plants, such as rutabagas, radishes, carrots, and sugar beets, the root is the crop. In some plants they also serve as a storage area for food for the plant. If not, please review the information at Roots are usually found underground with the functions of anchoring the plant and absorbing water and nutrients from the soil. For this lesson student's experience for eating fruits and vegetables that live and grow above ground or underground would be required for helping them gain an understanding for identifying where they belong on the USDA's MyPlate diagram. Teachers should be familiar with the MyPlate graphic organizer, including food categories. Farmers grow and harvest many plant-based foods such as carrots, green beans, kale, sweet potatoes, and strawberries which are part of a healthy diet.Įach of these food items are grown from a plant either above or below the surface of the soil. These plant foods can be an excellent teaching tool for understanding the external parts of a plant – roots, stems, leaves, fruits, and flowers. Plant-based foods provide essential nutrients including many vitamins and minerals.
