Heterocyst 5. They harvest the sun's energy, absorb carbon dioxide, and emit oxygen. The main difference between bacteria and cyanobacteria is that the bacteria are mainly heterotrophs while the cyanobacteria are autotrophs.Furthermore, bacteria do not contain chlorophyll while cyanobacteria contain chlorophyll-a. What is CYANOBACTERIA (plural noun)? Cyanobacteria all have some form of the green pigment chlorophyll, which is responsible for harvesting light energy during the photosynthetic process (Current Biology, 2014).
