Bacteriochlorophylls are photosynthetic pigments that occur in various bacteria. 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. Different groups contain different types of bacteriochlorophyll: A photosynthetic pigment is a pigment present in chloroplasts or photosynthetic bacteria which provides the energy necessary for photosynthesis. ...
