Across
  1. 2. distance between consecutive points of equal position
  2. 4. a complex (including chlorophyll) that is assembled around a special pair of chlorophyll molecules and a primary electron acceptor
  3. 6. group of proteins that forms the part of the electron transport chain between photosystem 1 and 2
  4. 10. photosynthetic pigment (yellow orange red) that functions to dispose of excess energy
  5. 12. organism that can build organic molecules using energy derived from inorganic chemicals instead of light
  6. 21. gaining of electrons by an atom or molecule
  7. 25. opening that regulates gas exchange and water evaporation between leaves and the environment
  8. 26. pigemnet molecule that directly absorbs light and transfers the energy absorbed to other pigment molecules
  9. 27. inner space of a thylakoid
  10. 28. where photosynthesis takes place
  11. 29. a stack of thylakoids
  12. 31. absorbs violet-blue light and red light, has a blue-green color; the only pigment molecule that performs the photochemistry by getting excited and losing an electron to the electron transport chain
Down
  1. 1. molecule that can absorb wavelengths of light
  2. 3. an oragnism that consumes organic substance or other substances for food
  3. 5. a range of all possible frequencies of radiation
  4. 7. accessory pigment that absorbs blue and red-orange light, yellow-green color
  5. 8. molecule (usually a pigment) that accepts the energized electron from the reaction center
  6. 9. complex that allows sunlight to pass to the reactions sites, has antenna proteins (mix of chlorphyll a and b along with other pigments like carotenoids)
  7. 11. uses light energy to transport electron through the ETC
  8. 13. reactions that do not require a photon of light to occur, ATP,NADPH, and CO2 are used to
  9. 14. ranges of wavelengths of electromagnetic radiation absorbed by a given substance
  10. 15. a group of proteins along photosystem 1 and 2 that can pass energized electrons, as this happens enough energy is made to pump hydrogen ions into the thylakoid lumen
  11. 16. transports electrons from water to the ETC, oxygen is produced
  12. 17. group of proteins , chlorophyll and other pigments that are used in the light dependent reactions
  13. 18. organism that can produce its own organic compounds using light
  14. 19. light-independent reactions of photosynthesis that convert carbon dioxide from the atmosphere into carbohydrates using the energy and reducing power of ATP and NADPH
  15. 20. process of converting CO2 gas into organic compounds
  16. 22. middle layer of chlorophyll-rich cells in a leaf
  17. 23. reactions that require a photon of light to occur, this photon is abosrbed to form two energy-carrying molecules(ATP and NADPH)
  18. 24. unit of light
  19. 30. membrane bound structure inside of the chloroplast where light dependent reactions take place
