Oxygen production of plants different at different times of the day due to presence of sunlight.
In cellular respiration, oxygen is taken in and carbondioxide is releases in the environment whereas in photosynthesis, carbondioxide is taken inside and oxygen is releases in the atmosphere so in this way matter is conserved during the processes of photosynthesis and cellular respiration.
Oxygen production of plants different at different times of the day because oxygen only produced when there is photosynthesis process which only occurs in the presence of sunlight. If plant was placed in a completely dark environment then there is no oxygen is produced and no photosynthesis occur.
