The primary pigment responsible for absorbing light energy in photosynthesis is chlorophyll.
Specifically, chlorophyll a is the primary pigment, while chlorophyll b and other pigments like carotenoids act as accessory pigments.
Chlorophyll 'a' is termed the primary pigment because it is the molecule in the chloroplast which directly involves in the absorption of light to provide energy for photosynthesis.
The other pigments like Chlorophyll 'b', Carotenoids, and Xanthophylls are accessory pigments
