Reply:I'm not sure what it is that you're asking, but the organisms known as "bacteria" comprise two very different types of living beings that belong to 2 different domains.


These "domains" are major divisions of life established on the basis of primary biochemical differences, including the composition of the cell wall and the morphology of some organeles inside these cells.





There are actually 3 domains. The Eukarya comprises all the organisms that have nuclei in their cells (from amoebas to ourselves). Our nucleated cells probably arose from symbiosis between the 2 types of prokaryotic cells listed below.





The other 2 domains are:


Bacteria: many of the better-known "true" bacteria belong here. Examples: Lactobacillus bulgaricus (the one in yoghurt), Salmonella (this one causes food poisoning).





Archaea: the archaeobacteria include some widely distributed species as well as many extremophiles (=able to live in extreme environments such as geisers, extreme salty places, etc.). Examples: Halobacterium, Methanobacterium
