The following: 1. The reason behind the more problematic definition of species in bacteria and Archaea as compared to the eukaryotes. 2. The present basis to define the prokaryotic species. Introduction: The tree of life has three domains, namely Archaea, bacteria, and eukarya. This tree of life is based on the SSU rRNA (small subunit ribosomal ribonucleic acid) analysis which was proposed by Carl Woese. The domains are represented above the kingdoms in this classification system. It identifies the domain Archaea to be more closely related to Eukaryotes than Prokaryotes.

What is the furthur classification of archaebacteria? On what basis it is classified.

For this assignment you will create a dichotomous key to help you Identify Bacteria (which are a pain in the bum to identify on the species level.) We will be focused on the general terms of bacteria and the only Phylum that will be addressed is the Cyanobacteria. Use the following to create a dichotomous key to begin to identify Bacteria: BACTERIA Bacillus Coccus Spirillium Phylum Cyanobacteria Gram (+) (-) Root nodules To Begin use the following question: Does the organism exhibit a membrane bound nucleus?

All of the following statements are true about the3-domain classification system EXCEPT:(a) The three domains are Bacteria, Archaea, and Eukarya.(b) Lateral gene transfer has forced us to rethink our do-main model from a “tree of life” to a “shrub of life.”(c) Domains are higher than the category of kingdoms.(d) Compared to Bacteria, Archaea inhabit the same en-virons and have the same amount of peptidoglycan intheir cell walls.(e) All of the above are true.
