  1. 1. The primary electron donor of Photosystem II.
  2. 4. It is a by-product of plants; its chemical symbol is O.
  3. 5. It is absorbed by plants in photosynthesis; also known as CO₂.
  4. 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.
  5. 8. It is used as food by the plant. It is produced inside the chloroplasts.

  1. 1. It is an electron transporter that transports electrons from photosystem II to cytochrome b₆f.
  2. 2. It is found in chloroplasts, mediates electron transfer, and contains an iron-sulfur cluster.
  3. 3. It provides the electrons and hydrogen ions needed to power the light-dependent and light-independent phases of photosynthesis; also known as H₂O.
  4. 6. It is light energy.
  5. 7. It is an energy-carrying molecule produced in the first stage of photosynthesis.
