उत्तर १
If a green plant is kept in bright light, it tends to use up all the CO2 produced during respiration for photosynthesis. Thus, the release of CO2 cannot be demonstrated. Hence, it is difficult to demonstrate respiration as these two processes occur simultaneously.
उत्तर २
When a plant is kept in sunlight, CO2 released by respiration gets used by photosynthesis to synthesise food. So no carbon dioxide is liberated, and respiration cannot be demonstrated.
