  1. 2. A magical green pigment that absorbs light and is found in all plants, algae, and cyanobacteria.
  2. 4. The organelle, or "mini organ," in plant cells and a few other eukaryotic cells that carries out photosynthesis, or the conversion of sunlight into food.
  3. 5. The state of a molecule that has gained electrons.
  4. 8. A negatively charged (-1) subatomic particle.
  5. 9. The range of wavelengths of the electromagnetic spectrum that is visible to the human eye.
  6. 12. A state of a molecule once it has lost an electron.
  7. 14. A biological molecule that has the elements carbon (C), hydrogen (H), and oxygen (O) in a ratio of 1:2:1.
  8. 15. Ribulose-1,5-bisphosphate carboxylase oxygenase, or the enzyme used in the light-independent reactions to fix carbon dioxide (CO2) to the 5-carbon ribulose-1,5-bisphosphate (RuBP).
  9. 18. The opening(s) or pore(s) in a leaf that allow the passing of gases into and out of the leaf.
  10. 20. The inner membrane space of a chloroplast.
  11. 21. The theory that explains how mitochondria and chloroplasts became organelles of other cells.
  12. 22. hetero = different (G); troph = feed (G)
  13. 24. A molecule that can donate electrons. A reducing agent reduces the molecule that it donates electrons to.
  14. 25. Hydrogen ion, otherwise known as a proton.
  15. 26. A membrane-bound compartment inside of the chloroplast where the light-dependent reactions of photosynthesis occur.
  16. 27. A molecule that accepts electrons and oxidizes the molecule that it accepts electrons from.
  17. 30. The first stage of photosynthesis, where light energy from the Sun is captured, and with a little help from our good buddy, water (H2O), changed into chemical energy in the forms of ATP and NADPH.
Down
  1. 1. The second stage of photosynthesis, where carbohydrates from carbon dioxide, or CO2, are produced using the energy forms (ATP and NADPH) generated in the first stage of photosynthesis
  2. 3. The process where ribulose-1,5-bisphosphate carboxylase oxygenase (RuBisCo), an enzyme, catalyzes the attachment of oxygen (O2) to the 5-carbon ribulose-1,5-bisphosphate (RuBP) in the stomata of plant leaves.
  3. 6. A specific process used in the light-dependent reactions of photosynthesis.
  4. 7. The movement of protons from the lumen to the stroma, or from high to low concentration, in chloroplasts.
  5. 10. An organism that consumes organic matter created by autotrophs.
  6. 11. Nicotinamide adenine dinucleotide phosphate, which is a strong reducing agent, or electron donor, as well as a coenzyme.
  7. 13. The process by which carbon dioxide (CO2) from the atmosphere is converted, or "fixed," into organic compounds (those containing carbon and hydrogen) using the energy from the Sun’s light. The byproduct of this process is oxygen (O2).
  8. 16. The inner area of a chloroplast where the light-independent reactions occur.
  9. 17. A series of reactions that occur during photosynthesis in the inner area, or stroma, of chloroplasts, aka the photosynthetic organelle in plants.
  10. 19. endo = inside; sym = with; biosis = life (G)
  11. 23. photo = light (G); synthesis = putting together (G)
  12. 28. Adenosine triphosphate. An adenine molecule, or a nucleotide, attached to three linearly connected phosphate groups (–H2PO4R, where R is a functional group). The breaking of chemical bonds between the 2nd and 3rd phosphate groups provides most of the chemical energy used by a cell.
  13. 29. An organism that can use light energy and the photosynthetic process to produce organic food (read: containing carbon and hydrogen) from inorganic molecules.
