Difference between Cyanobacteria and Bacteria
Cyanobacteria and bacteria are both prokaryotic single celled microorganisms, but cyanobacteria are a specific group known as blue-green algae. The primary difference is that cyanobacteria can perform photosynthesis due to their chlorophyll-containing cells, while typical bacteria cannot. This ability allows cyanobacteria to produce oxygen and is responsible for their characteristic […]
