  1. Roots

  2. What are the five functions of plant roots? • Absorption and transportation of nutrients and water • Anchorage • Storage of food and water • Vegetative Reproduction • Improve soil structure

  3. What are the three processes that allow the roots to absorb water and minerals? • Diffusion- the tendency of a substance to move from a high concentration to a low concentration. • Osmosis- the diffusion of water through a semi-permeable membrane. • Imbibition- absorption of water by dry materials. This is one of the reasons why plants can break apart rocks.

  4. What are the three kinds of roots? • Primary- first roots produced by a plant • Secondary- roots that branch off of the primary root. • Adventitious- arise from a non-typical root growing points.

  5. What are the different types of root systems? • Tap- one main root with secondary roots branching off • Fibrous- made up of many multi-branched roots.

  6. What type of irrigation system is needed for the different root systems? • Fibrous root need to be irrigated more frequently because they are shallower. • Tap roots need heavier, deeper irrigations because they are deeper.

  7. Root tip parts • Region of Cell Maturation: Behind growing point, area where secondary roots emerge. • Region of Cell Elongation: Rapid growth, absorption of large amounts of water. • Region of Cell Division: Growing point of root. Composed of meristematic cells. • Root Cap: Protective cells. • Root Hairs: absorb most of the water and minerals used by the plant.
