  1. Around the Worldin 40-ish questions

  2. Label this diagram Guard Cell ____________ _______________ Stoma

  3. Cellulose microfibrils on the guard cells are ______ oriented. radially

  4. The symplastis highly _______. dynamic

  5. Water in the xylem can travel in how many directions? a. One b. Two c. Depends on the amount of water d. Any direction a. One

  6. The symplast is the continuum of cytosol connected by the _____________. plasmodesmata

  7. How do guard cells regulate transpiration? By opening and closing the stomata

  8. Sugar in the phloem can travel in how many direction? a. One b. Two c. Depends on the amount of sugar d. Any direction d. Any direction

  9. What is the movement of organic molecules in plants called? Transduction Transportation Translocation transpiration c.Translocation

  10. Which plant hormone causes the closing of the stomata? a. Progesterone b. Abscisic acid c. Acetylcholine d. Dopamine b. Abscisic acid

  11. Which of these organic molecules are not present in the phloem sap? Amino acids Carbohydrates mRNA Hormones b.Carbohydrates

  12. Name the 2 ions or molecules that cause the guard cells to become turgid. K+ and H2O

  13. How fast can the phloem sap move? a. 1m/h b. 2m/h c. 2.4m/h d. it cannot be measured a. 1m/h

  14. What is required to load sugars into the sieve at the source? Photorespiration Transpiration Active transport Cell adhesion c.Active transport

  15. Plasmodesmata change in number and __________. permeability

  16. Plasmodesmata closes in response to cytoplasmic calcium levels, cytoplasmic pH or ____________. Turgor pressure

  17. What do you call the intake of CO2 and the removal of O2? Gas Exchange

  18. Plasmodesmata can form during _________ or much later cytokinesis

  19. Plasmodesmatacloses when the leaf loses its function during ___________. differentiation

  20. Which of the following are sugar sources? Pistol Stigma Anther Leaves d.Leaves

  21. Which of the following are sugar sinks? Ovule Sepal Roots Filament c.Roots

  22. How is the actual transport process of sugar in the phloem? Active Passive Transpirational Unnecessary b.Passive

  24. What are the two ways that the sugar can move? Apoplastic & Translastic Apoplastic & Symplastic Translastic & Respolastic Translastic & Symplastic b.Apoplastic & Symplastic

  25. Plant virus produce viral movement proteins that cause the plasmodesmata to _____. dilate

  26. Gas exchange only happens when sufficient amount of _____ is supplied. water

  27. Name the 3 environmental stimulus that cause open and closing of stomata. Light CO2 level internal clock

  28. What is the loss of turgor in a guard cell caused by? Water deficiency
