    Formative Questions

    1. Can unicellular organisms have tissues? Explain your answer.
    2. Why would a nucleus be required for an organism to be multicellular? What does this organelle allow cells to do?
    3. What is the function of a root?
    4. How does its structure contribute to that function?
    5. What is the function of a stem?
    6. How does its structure contribute to that function?
    7. What is the function of a leaf?
    8. How does its structure contribute to that function?
    9. What part of a plant do you think the following things you’d get at the grocery store are:
      • Onion
      • Potato
      • Ginger
      • Lettuce
      • Broccoli
    10. What do you think are the most important selection pressures on plants?
    11. Which of these do you think is the most important for determining plant anatomy and morphology? Explain your reasoning.

    Summative Questions

    1. What are the three main cell types in a plant?
    2. What are the three main tissue types in a plant, and what is a specific example of each?
    3. What is the function of the xylem tissue and which specialized cells are involved in this function? Was this a simple or complex tissue in the specimens you viewed?
    4. What is the function of the phloem tissue and how do the specialized cells in this tissue contribute to this function? Was this a simple or complex tissue in the specimens you viewed?
    5. One of the characteristics of living things is a hierarchical (nested) organizational structure. Organize the following terms into a nested structure: specialized cell, organ, organism, tissue, organelle.
    6. Open stomata result in water loss through transpiration. Why don’t plants just close their stomata to prevent water loss?
    7. How does the diameter of a conducting cell in the xylem influence the ability of the plant to take up water?
    8. What type of environmental conditions might select for a netted root system or a taproot system? Explain your answer.
    9. Why would a plant evolve to produce roots from stem tissue? What benefits does this provide the plant?
    10. What is the function of meristematic tissue? In what parts of a plant would you see meristematic tissue?
    11. Categorize the plant modifications described above as an adaptation in response to the following stressors. Briefly state how each modification helps the plant deal with the particular stressor.
      1. Water availability:
      2. Access to sunlight:
      3. Nutrient availability:
      4. Defense against herbivory
    12. How do you differentiate between a stem and a root? What about a stem and a leaf? Consider both macroscopic and microscopic options.
