Question

Differentiate between purple and green photosynthetic bacteria

Answer 1

Purple sulfur bacteria (PSB) arephotosynthetic and reduce carbon dioxide to carbohydrates using hydrogen sulfide instead of water. ...Green sulfur bacteria are strict anaerobes that are capable of photosynthesis. Green sulfur bacteriaabsorb longer wavelengths of light than purple sulfate bacteria.

Answer 2

ANSWER:

Purple sulphur bacteria reduce carbon dioxide to carbohydrate and Green sulphur bacteria are anaerobes and absorbs more light than PSB.

EXPLANATION:

Purple sulphur bacteria or PSB and Green sulphur bacteria or GSB both are capable of photosynthesis. PSB reduces the carbon dioxide to carbohydrates by hydrogen sulphide and not with water.

PSB shows septicity. Green sulphur bacteria or GSB on the other hand are photosynthetic anaerobes and absorbs more light than PSB. GSB can be found in sulphate containing atmosphere such as lagoons and wetlands.
