why does the green plants start evolving co2 instaed of oxygen in a whole summer da
huryyyyyyyyyyy fast

y?

Plants perform photosynthesis in day by fixing CO₂ (reducing it to a sugar; glucose) in the presence of sunlight and evolve Oxygen gas.

But if the temperatures are too high as in summer and more intensity of light the rate of photosynthesis increases leading to a marked rise in oxygen concentration.

Due to this increase in O₂ concentration, the plants undergo Oxidation through a photo respiratory cycle . In this photo respiration the plants lose CO₂ instead of oxygen
