When a plant undergoes photosynthesis, one of the by-products is oxygen. The correct option is D.
What is photosynthesis?
The process by which plants, algae, and some microorganisms convert sunlight, carbon dioxide (CO2), and water into food (sugars), oxygen, and other compounds is known as photosynthesis.
The chemical equation for photosynthesis is:
6CO₂ + 12H₂O + Light Energy → C6H₁₂O₆ + 6O₂ + 6H₂O
In order to assist in the creation of clean fuels and renewable energy sources, the general principles of photosynthesis are examined along with associated studies.
Carbon dioxide and water are the reactants that react and produce glucose and oxygen. Glucose is used by plants, but oxygen is not used by plants, so this is the byproduct.
Thus, the correct option is D. oxygen.
