Across
  1. 3. Pigment that absorbs light energy and becomes ionized.
  2. 4. Splitting of water using light energy into protons, electrons, and oxygen.
  3. 7. Enzyme that catalyzes the fixation of carbon dioxide with RuBP.
  4. 8. Folded membranes containing photosynthetic pigments (chlorophyll) where the light-dependent reaction occurs.
  5. 9. Stacks of thylakoids that increase surface area for light absorption.
  6. 10. Organisms (like plants) that produce their own food using light.
Down
  1. 1. Double-membrane organelle where photosynthesis occurs.
  2. 2. Process where light energy excites electrons in chlorophyll, causing them to be released.
  3. 5. Fluid-filled matrix surrounding grana where the light-independent reaction (Calvin cycle) occurs.
  4. 6. The mechanism of ATP production using a proton gradient across the thylakoid membrane.
