How do blue green bacteria differ from other bacteria?

Answer 1

Blue green bacteria are organisms in the phylum Cyanophyta. They used to be called blue green algae, but since their cells do not have nuclei they are now classified as bacteria. They are common in every aquatic or damp environment and some species can cause toxic blooms.

Answer 2

Cyanobacteria contain chlorophyll, in thykaloid membranes, for photosynthesis. In this way they are self sufficient. They create their own chemical energy source as autotrophs. They use solar energy by fixing carbon into an organic form to store chemical energy.

Other types of bacteria are chemotrophs like rizobacteria using nitrogen oxidation as an energy source. These are called Nitrosomonas and are autotrophic but not photoautotrophs like cyanobacteria. The purple sulfur bacteria are another chemoautotrophic bacteria class.

The rest of the bacteria are heterotrophs that consume energy autotrophs have fixed. These are osmotrophs. They secrete digestive enzymes onto the nutrient source then absorb what they need.

Answer 3

They are photosynthetic and as such are autotrophs and producers. Most other bacteria are consumers.

Answer 4

Unlike typical bacteria,these organisms can use photosynthesis to make food.

Answer 5

blue green algae is a type of bacteria
