  3. Functions of the Root System • The four major functions of roots are • Absorption of water and inorganic nutrients and transfer it to the other parts of the plant. • The roots hold the plant firmly, anchoring of the plant body to the ground, and supporting it. • Storage of food and nutrients like carrots and radish, root store food for the plants. • Vegetative reproduction.

  4. Tap Roots • Taproot is an enlarged, somewhat straight to tapering plant root that grows downward. It forms a center from which other roots sprout laterally. • Some plants with taproots: • Beets • Burdock • Carrot • Dandelion • Parsley • Parsnip • Poppy mallow • Radish • Sagebrush • Turnip
