Notes guidance and vocabulary for 9.1, Notes to be checked off on Thurs 5/12


  1. Be able to describe transpiration from leaf to root.  Include properties of water and xylem that make it possible.  Vocabulary to include:  stoma (stomata), guard cells, hydrogen bonds, cohesion, adhesion, hydrophilic, xylem, transpiration stream, transpiration pull, and more!!
  2.  Be able to describe the structure of xylem that allows it to withstand pressure and why transpiration through it must be passive.
  3. Outline the process of active transport of minerals in roots and how it leads to osmosis.  Describe the role of fungi and mass flow in assisting with the movement of ions to and into roots.
  4. Distinguish between symplastic and apoplastic movement of water from root hairs into xylem.
  5. Describe adaptations for water conservation in plants, including xerophytes and halophytes.  Give examples of each.  Include C4 physiology.
  6. Be able to draw and identify xylem vessels in sections of stems.  Draw pictures like Figures 14 and 16 and study figure 15 (p. 411)
  7. Models of water transport done in class:  capillary tubes and filter paper (paper towel)  (Can you design a good porous pot demonstration?  Do it for extra credit.)  Describe what happens with each and any limitations you notice.
  8. Describe how a potometer measures transpiration.
  9. Describe how you would design an experiment with a potometer to measure the effect of temperature, humidity, surface area of leaf, or wind on transpiration.
