Roots C9L3P3 Plant Organs

Types of organs in plants Roots Stems Leaves

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.

Functions of Roots Anchors Absorbs Transports Stores food

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

Two Types of Root Systems Taproots Fibrous roots

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

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

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

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

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

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

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

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