Across
  1. 2. the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
  2. 3. a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
  3. 4. compounds that absorb light
  4. 7. the initial reactions in photosynthesis, which are triggered by the absorption of light by photosystems 1 and 2 include the passageway pf electrons along the electron transport chains, the production of NADPH and oxygen gas, and the synthesis of ATP through chemiosmosis
  5. 10. a carbon-fixing process in which carbon dioxide is bound to a compound to form a four-carbon intermediate
  6. 12. a series of molecules, found in the inner membranes of mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane
  7. 15. a water-conserving, carbon fixing process; CAM plants take in carbon at night and fix it into various organic compounds and release it during the day
  8. 18. in chloroplasts, an acceptor of electrons lost from chlorophyll
  9. 19. converts light energy from the sun into chemical energy in the form of organic compounds, primarily carbohydrates
Down
  1. 1. a membrane system found within chloroplasts that contain the components for photosynthesis
  2. 2. in chloroplasts and mitochondria, a process in which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP
  3. 5. the process of plants rapidly losing water to the air through small pores
  4. 6. in plants, the solution that surronds the thylakoids in a chloroplast
  5. 8. a green pigment that is present in most plants cells, that gives plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates
  6. 9. a class of pigments that are present in the thylakoid membrane of plants and that aid in photosynthesis
  7. 11. in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions
  8. 13. a stack of thylakoids in a chloroplast
  9. 14. an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms
  10. 16. an organelle found in plant and algae cells where photosynthesis occurs
  11. 17. an organism that obtains organic food molecules by eating other organisms or their byproducts and that cannot synthesize organic compounds from inorganic materials
