In the 18th century, carl linnaeus published a system for classifying living things, which has been developed into the modern classification system. recently the classification system of life was changed to include not five but six kingdoms, as well as three domains. earlier classification attempts were based mostly on structural features. classification of many species, old and new, continues to be hotly disputed as scientists find new information or interpret facts in new ways. now, dna technology has allowed scientists to re-examine the relationships between organisms to refine the classification system. the kingdom monera in the old classification system included all bacteria. what two kingdoms now encompass prokaryotic organisms? a) bacteria and archaea b) eubacteria and archaea c) bacteria and archaebacteria d) eubacteria and archaebacteria eliminate

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.
