It produces glucose and oxygen and at daytime bothe photosynthesis and respiration happens whereas at night time only respiration happens because the is no sun for photosynthesis to happen.
The photosynthesis equation...
Carbon dioxide+ water > glucose +oxygen
The respiration equation...
Glucose + oxygen > carbon dioxide +water +energy
We can say that both respiration and photosynthesis are opposites.
