Across
  1. 3. An organism that makes its own food from inorganic sources (sunlight). Also called a producer.
  2. 6. Small openings in leaves that allow gases (CO₂ in, O₂ out).
  3. 7. The second stage of photosynthesis; use ATP and NADPH to convert CO₂ into glucose.
  4. 11. O₂; A gas released as a waste product during LR.
  5. 12. An organism that must consume other organisms or organic matter for energy. Also called a consumer.
  6. 13. Another name for autotrophs (e.g., plants, algae, phytoplankton, many bacteria).
  7. 15. A lower-energy molecule that can be converted into ATP (from CC back to LR).
  8. 16. A molecule that absorbs light of specific wavelengths (e.g., chlorophyll).
  9. 21. Series of proteins in the thylakoid that moves electrons to build up an H+ gradient (store energy)
  10. 22. H₂O; Absorbed by roots; split during the LR to release oxygen and provide electrons to ETC.
  11. 24. Another name for heterotrophs (e.g., animals, fungi).
  12. 25. CO₂; A gas from the atmosphere used as a carbon source in CC.
Down
  1. 1. Flattened membrane sacs inside the chloroplast where light-dependent reactions occur.
  2. 2. C₆H₁₂O₆; A sugar molecule produced in CC; used to make starch as food/energy for plants.
  3. 4. The ability of plant cells to capture gaseous carbon dioxide and convert it into solid glucose
  4. 5. The high-energy electron carrier formed in the light-dependent reactions (from LR to CC).
  5. 8. A green pigment in chloroplasts that absorbs light energy to power photosynthesis.
  6. 9. The organelle in plant cells where photosynthesis takes place.
  7. 10. Main energy currency of a cell that stores and transfers energy within cells (from LR to CC).
  8. 12. Lots of H+ ions stored in thylakoid space; this stored energy is transferred to make ATP at the end of the ETC in the LR
  9. 14. The first stage of photosynthesis; require light and occurs in the thylakoid membrane, producing ATP, NADPH, and O₂.
  10. 17. The process by which autotrophs use light energy, carbon dioxide, and water to produce glucose and oxygen.
  11. 18. The fluid-filled space inside the chloroplast where the Calvin Cycle occurs.
  12. 19. Describes organisms that can digest food without oxygen (often bacteria).
  13. 20. A carrier molecule that accepts electrons and hydrogen ions during photosynthesis (from CC back to LR).
  14. 23. Describes organisms that require oxygen to digest food.
