Answer :
Cyanobacteria contain many different colourants. Green light causes the production of additional phycoerythrin molecules, which promotes photosynthesis by allowing more green light to be absorbed.
What exactly are cyanobacteria?
Photosynthesis is the process through which the phylum of gram-negative bacteria known as cyanobacteria, or cyanophyta, generates energy. They are a member of a class of microorganisms that are related to bacteria and are capable of photosynthesis. They are believed to be the planet's first known prokaryotic life form.
What hues do cyanobacteria produce?
Phycobiliproteins (phycoerythrin, phycocyanin, and allophycocyanin), carotenoids (lutein, lycopene, astaxanthin, and fucoxanthin), and scytonemin are some of the photosynthetic pigments employed by cyanobacteria.
