What happens when the incident light on a plant is excessive?(a) RuBP

1.	What happens when the incident light on a plant is excessive?(a) RuBP undergoes oxidation(b) Vascular bundles lose functionality(c) Mesophyll cells are destroyed(d) Chlorophyll breaks downThis question was posed to me in class test.I would like to ask this question from Factors Affecting Photosynthesis topic in section Photosynthesis in Higher Plants of Biology – Class 11
Answer» Correct choice is (d) Chlorophyll breaks down The BEST I can explain: Light is rarely a limiting factor for photosynthesis, but excess amount of light REACHING the photosynthetic parts of PLANT causes the breakdown of chlorophyll and hence, REDUCES the RATE of photosynthesis.
