1. Roots C9L3P3 Plant Organs

2. Types of organs in plants Roots Stems Leaves

3. Roots Roots anchor a plant, either in soil or onto another plant or an object such as a rock. All root systems help a plant absorb water and other substance from the soil.

4. Functions of Roots Anchors Absorbs Transports Stores food

5. Roots Roots are the organs of the root system. A root system is all the roots of a plant.

6. Two Types of Root Systems Taproots Fibrous roots

7. Taproots commonly found in dicots penetrates the soil with very little branching often stores food (fleshy roots)

8. Taproots has one or a few main roots that are thicker and longer than the other roots of the plant examples: carrots and dandelions

9. Fibrous Root System commonly found in monocots have no main section but branch out into the soil in all directions

10. Fibrous Root System Has a cluster of roots that are approximately equal in size They branch several times Example: grasses

11. Parts of the Root Root cap – dead, thick-walled cells; for protection Epidermis - outer covering for protection, one cell layer thick Root Hairs - long, fingerlike projections of root's epidermal cells that greatly increase the root's water-absorbing surface area

12. Parts of the Root Xylem: has long, thick-walled cells which carry water and dissolved minerals upward (from roots up to stem and the leaves) Phloem: has cell walls, slightly thinner then xylem; it carries water and dissolved foods downward

13. Xylem and Phloem Water-conducting System (located near the center of the root) Xylem and phloem are usually arranged in fibrovascular bundles.

14. fibrovascular bundle xylem and phloem surrounded by supporting tissues; found in non-woody plants
