Class 11 NEET Biology Photosynthesis in Higher Plants

(c) : Plants can use a small portion of light which falls upon them. Chlorophyll-a and chlorophyll- b absorb too much light in the blue and red region. Carotenoids absorb light mostly in the blue region of spectrum of light. In monochromatic lights, maximum photosynthesis occurs in red light, followed by blue light and poor photosynthesis in green light. Under very high light intensity solarization phenomenon occurs. It involves photooxidation of different cellular components including chlorophyll.
