The Total solution for NCERT class 6-12
Suppose there were plants that had a high concentration of Chlorophyll b,but lacked chlorophyll a, would it carry out photosynthesis? Then why do plantshave chlorophyll b and other accessory pigments?
In the absence of chlorophyll-aphotosynthesis will not take place because chlorophyll-a is a reaction centreresponsible for the conversion of solar energy into chemical energy. Althoughchlorophyll is the primary pigment that traps sunlight but accessory pigmentslike chlorophyll-b, xanthophylls and carotenoids also absorb sunlight andtransfer energy to chlorophyll-a.
