ANSWER THE FOLLOWING QUESTIONS:

  1. Distinguish between photosynthesis and respiration.
  2. Distinguish between an action spectrum and absorption spectrum.
  3. Cite the two ways in which chloroplasts are produced in a green plant.
  4. Cite six structures of a green leaf and state the principal function of each.
  5. State how increased light intensity AND an increase in temperature affect the light and dark reactions during photosynthesis, and what occurs when the carbon dioxide supply is limited.
  6. State the general overall reaction occurring during the dark reaction phase of photosynthesis.
  7. State the principal function of light in photosynthesis.
  8. State the source of fluorescence in light-energized chlorophyll.
  9. Cite the principal reactions in photosystem I and in photosystem II, and state how the former is dependent on the latter.
  10. Explain how the structure of the chloroplast facilitates photosynthesis.
