What can cyanobacteria do that the bacteria living in your mouth do not do?

Answer 1

Probably the most obvious difference between cyanobacteria and the bacteria living in your mouth is the green color of cyanobacteria, pointing to probably the most important thing they can do that human oral bacteria cannot, and that is photosynthesis. Cyanobacteria have their characteristic color because of the chlorophyll pigment which allows them to convert light energy into food. Cyanobacteria can also form long filaments and sheets, which is something mouth bacteria cannot do. Cyanobacteria also produce toxins that are deadly to humans, something that oral bacteria obviously do not do, although recent research indicates that certain oral bacteria may help in the formation of atherosclerotic plaques, leading to possible Heart disease, so they may be dangerous to humans (besides tooth decay) for other reasons.

Answer 2

Cyanobacteria can perform photosynthesis to produce energy using sunlight, water, and carbon dioxide, whereas bacteria in your mouth do not possess this ability. Additionally, cyanobacteria can produce oxygen as a byproduct of photosynthesis, which is not a trait found in the bacteria in your mouth.

Answer 3

Preform photosynthesis and produce their own food.
