plants carry out both photosynthesis and respiration

photosynthesis: carbon dioxide + water = gluecose + oxygen (required energy)

respiration: glucose + oxygen = carbon dioxide + water (energy is released)

photosynthesis only occurs during the day, plants respire all the time

during the day they make more oxygen by photosynthesis than they actaully use in respiration. during the day
