Describe different types of photosynthetic pigments and explain their role.​

Dear student,

The major photosynthetic pigments are:
Chlorophylls: Chlorophyll a, b, c
Phycobilins: Phycoerythrobilin
Carotenoids: Carotenes, xanthophylls
Among them chlorophyll a is the chief pigment associated with photosynthesis and others are known as accessory pigments.
Also Phycobilins are mostly found in cyanobacteria and red algae while as chlorophylls and carotenoids are mostly found in plants. 
Chloroplasts are membranous structures (organelles) present in plant cells and contain chlorophyll and other photosynthetic pigments that help the plant in making its own food through photosynthesis.
Carotenoids helps with the oxidative stress faced by the plants during photosynthesis and in blue light spectra light absorption.
Phycobilin helps in light absorption in green, red, yellow and orange wavelengths.
