rait Plasmid Gram Staining Variable Results Species A Species C Species D SpeciesB None Species IE None Negative Photoautotroph Variable Negative Negative Chemoauto- troph Anaerobic methanogen (generates Nutritional Mode Chemohetero- Chemohetero- roph Chemohetero- troph troph Aerobic methanotroph (obtains carbon and energy frommethane) methane Specialized Metabolic Pathways Anaerobic fermentation Anaerobic fermentation Aerobic photosynthesis Internal membranes Internal Membranes Other Features Fimbriae Flagellum Pili Which species is most likely to be a cyanobacteria? A) species D B) species C C) species B D) species A E) species E

Explanation / Answer

The answer is Species E.

The cyanobacteria is aerobic photosynthetic bateria, which is a photoutotroph means they will synthesize their own food material using sun light, it also contains internal membranes. Plasmids are absent in cyanobacteria.
