1. WARM UP 1.List the 3 basic plant parts, the 2 tissue systems, and 1 of the types of ground tissue. 2.Write a 1-word description of each of the above. 1.List the 3 basic plant parts, the 2 tissue systems, and 1 of the types of ground tissue. 2.Write a 1-word description of each of the above.

2. Roots, Shoots, and Transport

3. Plant Transport Roots and Shoots move material through vascular tissue (tubes) –Xylem (water) –Phloem (sugar)

4. Root Systems Taproot –Deep primary root Fibrous –Many lateral roots

5. Root Functions Anchor Transport

6. Root Structure Root cap

7. Root Structure Root hairs Vascular cylinder

8. Absorption Root hairs –Surface area

9. Absorption Endodermis –Casparian strip –Selective permeability

10. Shoot Systems Vascular bundles in rings (dicots) or spread (monocots)

11. Shoot Functions Support Transport

12. Water Transport - Xylem Dead tubes (tracheids)

13. Water Transport - Xylem Cohesion-Tension Model –Transpiration (evaporation out of leaves) pulls on water –Water moves as a column due to cohesion and adhesion

14. Sugar Transport - Phloem Living –Sieve-tube members –Companion cells

15. Sugar Transport - Phloem Translocation –Sugar flows along a diffusion gradient

16. Sugar Transport – Phloem Pressure-Flow Model –Companion cells load sugar in phloem (source) –Water moves in (osmosis) –Pressure causes flow –Sugar and water out

17. WRAP UP Name the model of water transport. Name the model of sugar transport.
