Across
- 1. The primary electron donor of Photosystem II.
- 4. It is a by-product of plants; its chemical symbol is O.
- 5. It is absorbed by plants in photosynthesis; also known as CO₂.
- 6. It is a copper-containing protein that plays a role in the electron transport process associated with photosynthesis. It accepts electrons from cytochrome b₆f and passes to P700+ of photosystem I.
- 8. It is used as food by the plant. It is produced inside the chloroplasts.
Down
- 1. It is an electron transporter that transports electrons from photosystem II to cytochrome b₆f.
- 2. It is found in chloroplasts, mediates electron transfer, and contains an iron-sulfur cluster.
- 3. It provides the electrons and hydrogen ions needed to power the light-dependent and light-independent phases of photosynthesis; also known as H₂O.
- 6. It is light energy.
- 7. It is an energy-carrying molecule produced in the first stage of photosynthesis.
