UNIT OBJECTIVES:  Upon completion of this unit, the students will be able 
                  to:

1.  Diagram and label the five primary plant organs indicating the 
    functions of each (root, stem, leaf, flower, fruit).

2.  Compare and contrast monocot and dicot plants with respect to leaf, stem
    and flower structures.

3.  Diagram the transpiration and translocation systems of a plant.

4.  Describe the functions of the vascular cambium, xylem and phloem.

5.  Explain why knowledge of the vascular system of plants is necessary for 
    successful grafting.

6.  Describe and explain the effect of girdling on a woody plant.

7.  Distinguish between specialized roots, stems, and leaves (e.g., 
    stolons, rhizomes, bulbs, corms, and  tubers).

8.  Distinguish between roots and underground stems. 

9.  Sketch and label roots of carrots, potatoes, corms, and grasses.

10. Compare tap and fibrous roots systems.

11. Explain the function of stomata.

12. Explain how water affects the function of stomata.

13. Define transpiration.

14. Discuss four environmental factors that affect transpiration (e.g.,
    wind, humidity, temperature, solar radiation, and soil conditions).

15. Define the term hormone.

16. Describe how hormones are transported to target structures in plants.

17. Define translocation and its importance to the plant.

18. Trace the stages of development from germination to first seed leaf of
    bean, pea, onion, and corn.

19. Compare and contrast the types of growth of bean, pea, onion, and corn.

20. Describe the life cycle of a dicotyledonous plant from seed to seed 
    production.

21. Discuss the effects of photoperiodism on plant growth and give examples 
    of the effects.

22. Sketch and name three types of leaf arrangements on a stem.

23. List six basic growth requirements and indicate the importance of each
    (i.e., heat, mineral nutrients, water, light, gases, and support).

24. Distinguish between monocot and dicot plants with respect to 
    structure.

25. Trace the stages of development of seedlings from germination to the 
    stage of first true leaves.

26. Describe the life cycle of a dicotyledonous plant from seed to seed 
    production.

27. Discuss the environmental factors affecting plant growth (e.g., 
    temperature, water and humidity, light and wind).

28. List the requirements necessary for seed germination and indicate
    factors that might decrease germination rates (e.g., heat, water, 
    oxygen, seed dormancy, salt and disease).
