Final answer:
Plants use CO₂ (carbon dioxide) in photosynthesis to produce glucose and oxygen with the help of sunlight.
Explanation:
The gas used in the photosynthesis process is CO₂ (carbon dioxide).
During photosynthesis, plants utilize carbon dioxide (CO₂) and water (H₂O) to produce glucose (C6H12O6) and oxygen (O₂) in the presence of sunlight.
This process is crucial for the plant's survival and serves as a key mechanism for converting light energy into chemical energy.
