Difference between photosynthesis and photorespiration.

Photosynthesis is the process by which chlorophyll-containing cells synthesize food in the form of carbohydrates form carbon dioxide and water using sunlight.

Therefore, the raw materials required for photosynthesis are CO₂ and H₂O and the products formed are carbohydrates and O₂.

Hence, the process can be represented as:

Photorespiration is the light dependent process of oxygenation of ribulose biphosphate and release of carbon dioxide by the photosynthetic organs of a plant. Photorespiration consumes energy and leads to loss of fixed carbon dioxide in C₃ plants
