उत्तर
The photosynthesis in a plant is not taking place during the day time if the plant is releasing carbon dioxide.
Explanation:
During daytime, the carbon dioxide produced through respiration is used up in photosynthesis by leaves. In fact, more carbon dioxide is taken in from the air for this purpose. So, oxygen is diffused out and carbon dioxide is diffused in.
Hence, if a plant is releasing carbon dioxide during the daytime, it means the rate of photosynthesis is lower than the rate of respiration (or has stopped entirely).
