Question:
Oxygen liberated during photosynthesis comes from:
Oxygen liberated during photosynthesis comes from:
Show Hint
Photosynthesis occurs in plant chloroplasts where sunlight, water, and carbon dioxide are converted into glucose and oxygen.
Updated On: Mar 25, 2025
- Carbon dioxide
- Water
- Break down of Chlorophyll
- Atmosphere
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
During photosynthesis, oxygen is liberated as a byproduct, which comes from the splitting of water molecules (H₂O) in the process of photolysis.
