Why are bacteria and cyanobacteria classified together in the kingdom eubactera? And how are they different?

First of all, cyanobacteria are a KIND of bacteria, like


corn is a kind of plant or spiders are a kind of animal.





All living things are in one of 3 domains. These are


Eukarya, Bacteria and Archaea.





All living things are in one of 6 kingdoms. These are


Animalia, Plantae, Fungi, Protista, Eubacteria and


Archaebacteria. The kingdom eubacteria includes


exactly the same things as the domain bacteria, so


you could say bacteria and eubacteria are 2 names


for the same thing. Similarly, the domain archaea


is the same as the kingdom archaebacteria.





Cyanobacteria, is a sub-type of the domain bacteria


and thus also a sub-type of the kingdom eubacteria.





One property of the cyanobacteria is that they can


produce their own food by photosynthesis. This is


one thing these bacteria have in common with the


members of the kingdom Plantae, the plants. Most


bacteria are not able to do this.





Warning: There is an alternative classification of all


living things into 5 kingdoms. These are Animalia,


Plantae, Fungi, Protista, %26amp; Monera. Monera consists


of the Eubacteria and Archaebacteria put together


in one group with a single name.
