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

2. Roots, Shoots, and Transport

3. Root Systems
Taproot
Deep primary root
Fibrous
Many
lateral roots

4. Root Structure
Root cap

5. Root Structure
Root hairs
Vascular cylinder

6. Root Functions
Anchor
Absorption

7. Root Functions
Absorption
Surface area

8. Root Functions Absorption Endodermis Casparian strip
Selective permeability

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

10. Shoot Functions
Support
Transport

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

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.

18. Compare and contrast the structure of stems and roots.
WARM UP
Compare and contrast the structure of stems and roots.

19. Compare and contrast the structure of monocot and dicot stems.
WARM UP
Compare and contrast the structure of monocot and dicot stems.
