Question

why we cannot conduct an experiment on plant respiration during daytime​

Answer 1

Answer:

Plants conduct photosynthesis during daytime and respiration during night time. Thus, we will not be able to conduct respiration experiments during daytime as there is no respiration during daytime.

Answer 2

Answer:

We cannot conduct an experiment on plant respiration during daytime​ because during daytime they carry out photosynthesis and thus the carbon dioxide is released during respiration gets absorbed during photosynthesis and the oxygen released during photosynthesis gets absorbed during respiration.
