Q. Beyond of saturation point, the photosynthesis begins to decline because of I. Photo inbibition II. Photo-oxidation III. Photo-reduction Select the/correct option which matches with statement
A) I and III
B) III and II
C) I, II, and III
D) I and II
Explanation
Beyond the saturation point (seldom seen in $C_{4}$-plants), the rate of photosynthesis begin to decline. This process is called solarisation. It is due to the reduction in hydration and closure of stoma (photo-inhibition) or oxidation of photosynthetic pigment (photoxidation)
