“All plants give out oxygen during day and carbon dioxide during night”. Do you agree with this statement? Give reason.

(N/A) No,this statement is not entirely correct.
During the day,plants perform both photosynthesis and respiration. Since the rate of photosynthesis is significantly higher than the rate of respiration,the net result is the release of oxygen.
At night,photosynthesis stops because there is no sunlight,but respiration continues. Therefore,plants only release carbon dioxide at night.
Thus,while the statement is partially true regarding the net gas exchange,it is inaccurate to say plants 'only' give out oxygen during the day,as they are also respiring.
