Is it true that at night, plants TAKE away oxygen? Like almost all living things, plants use oxygen for their processes all the time. During the day, photosynthesis uses light to produce oxygen from carbon dioxide in excess of the plant's needs. At night, the living processes continue to use O2 but little or no CO2 is being converted. On the whole, the daylight production overwhelms the nght time use so there is considerable net production each day.
