Photosynthesis Questions and Answers

Here are 30 one-liner questions and answers on the keyword “Photosynthesis”:

1. What is photosynthesis? – The process by which plants convert sunlight into energy.
2. Where does photosynthesis occur? – In the chloroplasts of plant cells.
3. What is the primary pigment in photosynthesis? – Chlorophyll.
4. What are the two main stages of photosynthesis? – Light-dependent reactions and Calvin cycle.
5. What gas is released during photosynthesis? – Oxygen (O₂).
6. What gas is absorbed during photosynthesis? – Carbon dioxide (CO₂).
7. What is the primary energy source for photosynthesis? – Sunlight.
8. What is the end product of photosynthesis? – Glucose (C₆H₁₂O₆).
9. Which organelle is responsible for photosynthesis? – Chloroplast.
10. What is the role of water in photosynthesis? – It provides electrons and hydrogen ions.
11. What is the chemical equation for photosynthesis? – 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
12. What is the Calvin cycle also known as? – The light-independent reactions.
13. What is photolysis in photosynthesis? – The splitting of water molecules by light.
14. What are the byproducts of photosynthesis? – Oxygen and glucose.
15. Why is photosynthesis important for life on Earth? – It produces oxygen and food.
16. Do all plants perform photosynthesis? – No, some parasitic plants do not.
17. Can photosynthesis occur in artificial light? – Yes, if the light has the right wavelengths.
18. What is the role of NADPH in photosynthesis? – It carries high-energy electrons.
19. What is the role of ATP in photosynthesis? – It provides energy for the Calvin cycle.
20. What are stomata’s role in photosynthesis? – They allow CO₂ to enter and O₂ to exit.
21. Which part of the leaf absorbs sunlight? – The chlorophyll in the mesophyll cells.
22. What happens if a plant gets no sunlight? – Photosynthesis stops, and it cannot make food.
23. How does temperature affect photosynthesis? – Too high or too low temperatures can slow it down.
24. What is the difference between photosynthesis and respiration? – Photosynthesis makes glucose; respiration breaks it down.
25. Can algae perform photosynthesis? – Yes, they contain chlorophyll.
26. What is the role of rubisco in photosynthesis? – It fixes CO₂ in the Calvin cycle.
27. What is the significance of the thylakoid membrane? – It houses the light-dependent reactions.
28. Why do leaves appear green? – Because chlorophyll reflects green light.
29. What is CAM photosynthesis? – A water-saving adaptation in desert plants.
30. How does photosynthesis help reduce global warming? – It absorbs CO₂, a greenhouse gas.
