Root system is the portion of a plant below the surface of the soil.
Roots function in anchorage, water and mineral uptake and storage of photosynthetic products.
Two-thirds of a plant is usually below ground. Roots may be classified as taproot or fibrous roots. The Shoot system is the portion of a plant above the ground, including the stem, the leaves, flowers and fruits. The stem functions in support and positioning of leaves, and other organs such as flowers and fruits. A stem mainly serves as a connection between the roots and its lateral appendages.
