Photosynthesis Worksheet 1. What is the overall reaction for photosynthesis? 6 CO₂+6H₂O glucose (CHO) +60 2. Where does the energy for photosynthesis come from? from sunlight 3. In what organelle of a plant cell does photosynthesis take place? in the chloroplasts 4. What are the two stages of photosynthesis? light reactions and Calvin cycle 5. In which part of the chloroplast does each stage occur? The light reactions take place in the thylakoids, The Calvin cycle takes place in the stroma. 6. What happens to water molecules in the light reactions? Water molecules (H:O) are split to give electrons, H ions, and oxygen gas (O2). 7. What two products of the light reactions are used up in the Calvin cycle? ATP and NADPH 8. What happens to carbon dioxide molecules in the Calvin cycle reactions? In the Calvin cycle, carbon dioxide molecules (CO₂) are combined with each other and with the electrons and H's from NADPH to form glucose (C₂H₂O). 9. Label the diagram below to summarize the two stages of photosynthesis. Use the word bank below the diagram to fill in the blanks. 1. light 2. H2O 3.
