When you have finished this page, try the Roots Quiz. The root is the part of a plant that is usually found underground but can also be above ground. Roots' jobs are: To absorb or take in water and minerals from the ground. To hold the plant in place. To store food for the plant. To prevent soil erosion.
The root system is below ground. This system includes roots, tubers (an enlarged, fleshy, underground stem with buds capable of producing new plants) and rhizomes (a horizontal stem that is usually underground and roots grow from it.) Roots anchor the plant in soil so that it doesnât fall over. Root are much like straws through which water and minerals from the soil move upward to the shoot system. Tiny root hairs stick out of the root, helping in the absorption. Roots also store extra food for future use.
