Question

During the day plants take carbon dioxide and give out oxygen. But plant also take in oxygen and give out carbon dioxide all the time. How do you explain that?

Answer 1

Explanation:

during day respiration and photosynthesis both process take place simultaneously. photosynthesis take place only during day but respiration take place all time. the part of oxygen released during photosynthesis is used by plant in respiration and thus a relative amount of oxygen is greater. part of carbon dioxide released during respiration is used by plant during photosynthesis. so on an average during day oxygen is given out by plant and carbon dioxide is taken by plant.but at night only respiration takes place socarbon dioxide is given out and oxygen is taken.
