  1. The grana are the organelles that carry on photosynthesis in a plant cell.
    False.
  2. The light reactions of photosynthesis provide
    chemical energy.

    The light reactions of photosynthesis provide chemical energy in the form of ATP.
  3. In the overall equation for photosynthesis, the reactants are
    water and carbon dioxide.
  4. Which of the following is true regarding the light reactions of photosynthesis?
    Green light is not absorbed by the photosynthetic pigments
  5. The reaction center of chlorophyll a is an area where solar energy is concentrated.
    True
  6. During the light reactions, ATP is produced when
    hydrogen ions move from the thylakoid space to the stroma.
  7. The first step of the Calvin cycle is
    the attachment of carbon dioxide to RuBP.
  8. The NADPH made in the light reactions is used to produce the ATP used in the Calvin Cycle Reactions.
    False

    The NADPH made in the light reactions is used for the reduction of carbon dioxide in the Calvin Cycle Reactions.
  9. Which of the following is not true regarding the Calvin cycle?
    Water is used during the reactions.
  10. The G3P produced during the Calvin Cycle Reactions can be used by plants to make all of the following except?
    water.
  11. Cellulose, a structural component of plant cell walls, in an important energy source in the human diet.
    False.
  12. Which of the following is true regarding C3 photosynthesis?
    The first molecule formed after CO2 fixation is composed of three carbons.

    In C3 photosynthesis, the first molecule formed after CO2 fixation is composed of three carbons.
  13. When the weather is hot and dry, C4 plants predominate because
    an enzyme involved in CO2 fixation is not exposed to oxygen.
  14. CAM photosynthesis
    conserves water for the plant.

    CAM photosynthesis conserves water for the plant.
  15. CAM plants compete well with C3 and C4 plants when the environment is extremely arid
    True
  16. Both cactuses and orchids have evolved CAM photosynthesis.
    True.
  17. The pigments found within most types of photosynthesizing cells are ______?
    chlorophylls and carotenoids
  18. Photosystem II (PS II), Photosystem I (PS I), and the electron transport chain are located within molecular complexes in the ___________?
    thylakoid membrane
  19. In reference to the overall equation of photosynthesis, the gain of hydrogen atoms results in the ___________ of CO2?
    Reduction
  20. In a cold climate, more C3 than C4 plants would likely be found.
    True.

    In a cold climate, more C3 than C4 plants would likely be found.
