Question
The oxygen in glucose comes from _______ during photosynthesis.
- Carbon dioxide
- (CO2) Water
- Both water and carbon dioxide are used.
- Sunlight
Hint:
The gas that is release during respiration.
The correct answer is: Carbon dioxide
- Photosynthesis is the process by which plants take carbon dioxide and water and convert them into food and release oxygen in the presence of sunlight
- During the process, water is oxidized and carbon dioxide gets reduced
- As a result, water is converted to oxygen and carbon dioxide is converted into glucose or sugar
