Across
  1. 2. Reaction in which light energy breaks down a molecule.
  2. 3. Distance between crests of two successive waves of radiant energy.
  3. 4. Packets where electromagnetic energy of light is organized.
  4. 6. Makes sugars from carbon dioxide and water (sunlight energy)
  5. 8. The semifluid matrix between the thylakoid membrane and the two outer membranes of a chloroplast, site of light-independent photosynthesis reaction.
  6. 9. An organic molecule that absorbs light of certain wavelengths.
  7. 12. Any light-driven phosphorylation reaction.
  8. 13. They make their own food by using the environment.
  9. 15. A chloroplast's inner membrane system, often folded as flattened sacs that form a continuous compartment in the stroma.
Down
  1. 1. Cluster of pigments and proteins that, as a unit, converts light energy into photosynthesis.
  2. 4. The metabolic pathway by which photoautotrophs capture light energy, and use it to make sugars from carbon dioxide and water.
  3. 5. Organelle of photosynthesis in plants and some protist.
  4. 7. Adenosine triphosphate, nucleotide that consists of an adenine base, the five carbon sugar ribose, and three phosphate groups. Main energy carrier between reaction sites in cells.
  5. 10. Main photosynthetic pigments in plants, algae, and cyanobacteria.
  6. 11. Organic pigments that are found in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms
  7. 14. Coenzymes that accept electons and hydrogen ions.
