  1. After entering the root hairs, what part of the plant will water into next?
    Xylem
  2. The tension that pulls water from the stems into the leaves
    Cohesion
  3. The process in which water evaporates through stomata in the leaf. (loss of water of plants)
    Transpiration
  4. Does every epidermal cell have a root hair?
    No
  5. What are the two conducting cells in the xylem?
    Tracheids and vessel elements
  6. After exposing celery stalks to air, What do the results indicate about a continuous water column versus a water column with air interrupting the column?
    Continuous water allows for more rapid movement
  7. What type of tissue in the celery stalk was stained by the dye?
    Xylem
  8. Why was the xylem the tissue that was dyed in the celery stalk experiment?
    Water moves through the xylem
  9. When the stem of carnation is submerged in dye, which part of the flower is the dye located in?
    Veins in pedals
  10. What can be concluded about the movement of water in the plant?
    Transpiration occurs in the flowers and leaves
  11. How do the turgid guard cells of Crassula form a stomatal pore?
    Bow and form opening to create the pore
  12. Did NaCl solution cause the stomata to close? Why or why not?
    Yes, because the cell was put into a hypertonic solution, and it became flaccid
  13. What is the advantage of closed stomata when water is in short supply?
    The plant can preserve water
  14. What is the disadvantage of a closed stomata when water is in short supply?
    No gas exchange
  15. Nutrients needed in relatively large amounts
    Macronutrients
  16. What are some examples of macronutrients? (3)
    • Nitrogen
    • Phosphorus
    • Calcium
  17. Nutrients needed in relatively small amounts
    Micronutrients
  18. What are some examples of micronutrients? (3)
    • Iron
    • Chlorine
    • Copper
  19. How would you cure a plant suffering from these deficiency symptoms?
    Provide them with the nutrients
  20. Why are certain deficiencies either localized to or appear in certain areas of the plant? (2)
    • Each nutrient has a mobile ability
    • Iron is deficient in new leaves because its immobile
