  1. ROOTS Parts of the Plant

  2. Parts of the Plant: Roots

  3. Functions of Roots • 1. anchor the plant and hold it upright. • 2. absorb moisture and minerals from the soil and conduct them to the stem. • 3.Storage of plant food.

  4. Functions of Roots continued • In some plants, but not all plants... • 4. propagate or reproduce the plant • 5. can be used for food: vegetables: carrots, beets,

  5. The Anatomy of a Root

  6. Root cap – covers the tip of the root and protects it as it pushes through the soil. • New cells are produced under the root cap by meristem tissue through mitosis. • This addition of cells is how a root grows.

  7. Root hairs – are the actual point of moisture absorption. • The root system of a typical tree develops a root system that extends in all directions as far as the tree is tall or more...

  8. Types of Root Systems • Plants generally conform to one of two types of roots systems: • Tap Root System • Fibrous Root System

  9. Types of Roots • Fibrous- located near soil surface. Made up of many tiny roots with short branches.

  10. Fibrous rooted plants - are the easiest type of plants to transplant. • The many “tiny” roots all have root hairs (are the actual point of moisture absorption) • Makes it easier for the plant to recover from root loss. • Most monocots have fibrous root systems.

  11. Types of Roots • Tap Root- one main root, below the soil surface, several others branching out to the sides.

  12. Types of Roots • Aerial Roots- develop from the stem and project downward into the soil. Help to support a plant. • Called 'aerial roots' because they begin above ground • Found on corn, banyun, weeping fig, sugar cane

  13. Examples of Aerial Roots

  14. 2 • Adventitious Tissue - not actually roots. Function to support plants onto other surfaces. • Have the potential for becoming roots. • Generally develop from underneath leaves at the nodes.
