Across
- 4. – Membrane inside the chloroplast where light reactions occur
- 7. – Fluid-filled space outside the thylakoid membrane
- 9. – Energy from the sun that powers photosynthesis
- 10. – Process of splitting water into electrons, hydrogen ions, and oxygen
- 13. – Second photosystem that re-energizes electrons
- 14. – Gas released as a byproduct of water splitting
- 15. – Positively charged particles (H⁺) that build up in the thylakoid
Down
- 1. – Organelle where photosynthesis takes place
- 2. – Series of proteins that transfer electrons and release energy
- 3. – First protein complex that captures light and splits water
- 5. – Sugar molecule produced as a product of photosynthesis
- 6. – Movement of H⁺ ions through ATP synthase to produce ATP
- 8. – Gas taken in by plants as a reactant
- 11. – Negatively charged particles energized by light
