Answer 2

Bacteriochlorophylls are photosynthetic pigments that occur in various phototrophic bacteria. They were discovered by C. B. van Niel in 1932. They are related to chlorophylls, which are the primary pigments in plants, algae, and cyanobacteria. Groups that contain bacteriochlorophyll conduct photosynthesis, but do not produce oxygen. They use wavelengths of light not absorbed by plants or Cyanobacteria. Different groups contain different types of bacteriochlorophyll:

Pigment Bacterial group in vivo infrared absorption maximum (nm)

Bacteriochlorophyll a Purple bacteria, Heliobacteria, Green Sulfur Bacteria, Chloroflexi, Chloracidobacterium thermophilum[1] 805, 830–890

Bacteriochlorophyll b Purple bacteria 835–850, 1020–1040

Bacteriochlorophyll c Green sulfur bacteria, Chloroflexi, C. thermophilum 745–755

Bacteriochlorophyll cs Chloroflexi 740

Bacteriochlorophyll d Green sulfur bacteria 705–740

Bacteriochlorophyll e Green sulfur bacteria 719–726

Bacteriochlorophyll f Green sulfur bacteria (currently found only through mutation; natural may exist)[2] 700–710

Bacteriochlorophyll g Heliobacteria 670, 788
