Why is it usually difficult to demonstrate respiration in green plants?
Advertisements
उत्तर
During day time, both photosynthesis and respiration takes place in green plants. Evolution of CO2 is an indicator to demonstrate respiration in living organisms. CO2 produced during respiration in plants gets utilized during photosynthesis and thus, there is no evolution of CO2. Therefore, it is difficult to demonstrate respiration in green plants as there is no evolution of CO2 during day time.
