Presentation transcript:

Function of Roots Absorbs water and minerals Anchors plant Stores food and water

Type of Root Systems 1. Tap Root- dominant, primary root, deep penetration into soil 2. Fibrous Root- no primary root, spreads out near surface of soil

3. Adventitious Roots Roots that form from any other part of the plant other than the radicle (first root) Roots from bulbs, corm, tubers, rhizomes, stolons and cuttings of leaves and stems

4. Buttress root: extends above ground from base for support

5. Prop root: arises from stem for support

6. Pneumatophores: roots grow up and out of water for gas exchange

7. Tuberous Root: Grows close to stalk

8. Root Nodules: Root structures of legumes plants that contain nitrogen fixing bacteria.

Flower Pot Plant An epiphyte plant (tropics) that has aerial roots that grow into modified leaves (flower pot) that catches water.
