Across
  1. 8. An organism that gets energy by consuming other organisms for its energy and nutrition.
  2. 10. Processes that happen without oxygen.
  3. 13. Molecule in chloroplasts that accepts high-energy electrons.
  4. 14. A sac inside chloroplasts where light reactions occur.
  5. 16. CAM (Crassulacean Acid Metabolism). An Adaption some plants use to store CO2 at night for daytime photosynthesis.
  6. 18. A molecule that absorbs light, giving color to plants.
  7. 19. Process of converting CO2 into organic compounds, like in photosynthesis.
  8. 20. Respiration that uses oxygen to produce energy.
  9. 21. Organelle in plant cells and some algae where photosynthesis takes place.
  10. 23. An anaerobic process that follows glycolysis, making lactic acid or alcohol.
  11. 26. Red, orange, or yellow pigments that help in photosynthesis.
  12. 27. Series of reactions in mitochondria that produce energy and CO2 during aerobic respiration.
Down
  1. 1. Tiny openings on leaves that let CO2 in ad O2 out.
  2. 2. Process where cells break down food (carbon compounds) to make energy or ATP.
  3. 3. Type of fermentation that makes alcohol and CO2, as seen in yeast and some bacteria.
  4. 4. Process where Carbon is taken from the air by green plants, algae, and some bacteria. It makes glucose from sunlight, water, and carbon dioxide.
  5. 5. Type of fermentation that makes lactic acid, common in muscles.
  6. 6. First part of photosynthesis where light energy becomes chemical energy. This occurs in the thylakoid membranes of chloroplasts.
  7. 7. A stack of thylakoid membranes in a chloroplast.
  8. 9. Green pigment found in chloroplasts.
  9. 11. Series of molecules found in the mitochondria and chloroplasts that move electrons to make energy.
  10. 12. An organism that makes its own food, like plants, through photosynthesis or chemosynthesis
  11. 15. Fluid in chloroplasts around the grana (thylakoid stacks), where the Calvin Cycle (light-independent reactions) happens.
  12. 17. The first stage of cellular respiration in which glucose is broken down into pyruvic acid and ATP.
  13. 22. A 3-carbon molecule formed during glycolysis, important in cellular respiration.
  14. 24. Group of pigments and proteins in chloroplasts that capture light energy.
  15. 25. Part of photosynthesis where CO2 is turned into glucose using ATP energy.
