  1. What are the first two stages of photosynthesis called?  They take place only in the presence of light.
    light-dependent reactions
  2. What is the third stage of photosynthesis called?  It is the formation of organic molecules from atmospheric carbon dioxide and doesn't require light directly.
    • Calvin cycle
    • light-independent reactions
  3. In the membranes of thylakoids, chlorophyll pigments are grouped together in what network?
  4. Light consists of what tiny packets of energy?
  5. What is the full range of photons called?
    electromagnetic spectrum
  6. What are the photons that our eyes perceive called?
    visible light
  7. What are molecules that absorb light energy called?
  8. What is the pigment within human eyes called?
  9. What are the other pigments that plants contain called?
    accessory pigments
  10. What is the group of pigments that capture violet to blue-green light called?
  11. The excitation energy is funneled to a key chlorophyll a molecule called what?
    reaction center
  12. What is the series of electron-carrier molecules embedded in the membrane that the excited electron is shuttled along called?
    electron transport system
  13. What is the two-stage process that plants use to produce ATP and NADPH called?  It is called this because the path of the electron is not a circle.
    noncyclic photophosphorylation
  14. What is the portion of the photosystem that contains all the pigment molecules called?
    antenna complex
