0 the process by which a plant takes oxygen from the light of the sun and produces carbon dioxide :
Without photorespiration, the plant struggles for nourishment.
Photorespiration happens because the enzyme that powers photosynthesis has trouble distinguishing between carbon dioxide and oxygen molecules.
In photorespiration, plants take up oxygen and release carbon dioxide without making food.
The chemical reactions, collectively called photorespiration, may explain why some plants don't fare well under global warming.
Scientists have been trying to genetically engineer plants with a better ability to discriminate between oxygen and carbon dioxide, thereby suppressing photorespiration.
