Across
  1. 5. the discrete particles of light
  2. 7. B, the accessory pigment
  3. 10. complex, consists of various pigment molecules bound to proteins
  4. 12. electron acceptor, a molecule capable of accepting electrons and becoming reduced
  5. 14. “self-feeders”
  6. 15. organisms that use light energy to drive the synthesis of organic molecules from carbon dioxide and (in most cases) water.
  7. 16. through which carbon dioxide enters the leaf, and oxygen exits
  8. 18. nicotinamide adenine dinucleotide phosphate
  9. 20. organisms that are unable to make their own food
  10. 21. the instrument that measures the ability of a pigment to absorb various wavelengths of light.
  11. 27. complex, organized association of proteins holding a special pair of chlorophyll a molecules
  12. 28. where chloroplasts are found
  13. 29. when light reactions are used to generate ATP, using chemiosmosis to power the addition of a phosphate group to ADP.
  14. 30. a dense fluid within the chloroplast
Down
  1. 1. green pigment that gives leaves their color.
  2. 2. spectrum, the entire range of radiation
  3. 3. A, the type of pigment that participates directly in the light reactions,
  4. 4. light, the radiation most important to life or the narrow band from about 380 nm to 750 nm in wavelength
  5. 6. the distance between the crests of electromagnetic waves
  6. 8. where chlorophyll molecules are organized along with other small organic molecules and proteins into these complexes.
  7. 9. made up of this in the third membrane system
  8. 11. I, a protein complex in the thylakoid membranes of photosynthetic organisms that uses light energy to transport electrons across the membrane which functions second in the light reactions.
  9. 13. spectrum, profiles the relative effectiveness of different wavelengths of radiation in driving the process
  10. 17. spectrum, the graph plotting a pigment’s light absorption versus wavelength
  11. 19. II, a protein complex in the thylakoid membranes of photosynthetic organisms that uses light energy to transport electrons across the membrane which functions first in the light reactions.
  12. 22. the process where solar energy is converted into chemical energy in plants
  13. 23. hydrocarbons that are various shades of yellow and orange because they absorb violet and blue-green light.
  14. 24. reactions, the first stage of photosynthesis
  15. 25. Cycle, the second stage
  16. 26. fixation, the initial incorporation of carbon into organic compounds
