Plants are able to produce oxygen through the process of photosynthesis and photosynthesis is well carried in the presence of light at a warm temperature of 28 degree Celsius. The rate of photosynthesis falls if the temperature rises above 28 degree Celsius and with falling rate of photosynthesis, rate of oxygen production also falls.
The rate of photosynthesis and hence the oxygen produces also falls when the temperature falls below 28 degree celsius.
