Kingdom Bacteria Vs Archaea

Bacteria are single celled organisms. Some classify them as a separate (fourth) kingdom on the tree of life.

Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body, only 1% of bacteria is actually harmful.

First things first, taxonomy is the identification, description and the naming or nomenclature of organisms. The two domains are Bacteria and Archaea. Archaea is most related animals and plants also metabolic pathways. Bacteria most related to human pathogens and soil or dirt. The Domains are put together by genetic characteristics. Where Archaea for the most part are primitive and are adapted for extreme habitats and modes for nutrition we can see some similarities, with bacteria that also can live in extreme environments like thermal vents. The two might be cut from the same cloth and both are needed for life on earth to happen the most looked at for us is bacterial because that is the most harmful to

Bacteria and Archaea are prokaryotic, which are mostly single-celled incomplex microorganisms. Both Bacteria and Archaea have a variety of prokaryotes classified in multiple kingdoms (Reece, et al., Campbell Biology, 2014). There are a number of scientists who believe that Archaea cells may be the precursor to Eukaryotic cells and that they have more in common with Eukaryotes than Prokaryotes (Madigan, Martinko, & Dunlap, 2009).

Escherichia Coli is a rod-shaped bacterium that measures approximately 0.5 μm in width by 2 μm in length. It is a Gram-negative bacterium. Its cells stain gram negative because they have a thin cell wall with only one to two layers of peptidoglycan. They live in environments with higher temperatures rather than cooler temperatures. E. coli is said to be the “model organism”. Many microbiologists use these bacteria as a resource for understanding other prokaryotic life and are the most carefully studied life form on the planet. It was discovered by German-Austrian pediatrician Theodor Escherich in 1885.

When we speak of the word “bacteria” some individuals may not recognize how large of a role these tiny organisms play in our everyday lives. Some may jump to the conclusion that bacteria are related to the spread of germs or sickness among the human population. Most microbes are harmless or beneficial (Matthews, 2015) and a large majority of these tiny microbes are extremely important in order to maintain the balance of living organisms and chemicals in our environment (Tortora, Funke, & Case, 2013).

E. coli, Bacteria (Domain), Proteobacteria (Phylum), Gammaproteobacteria (Class), Enterobacteriales (Order), Enterobacteriaceae (Family), Escherichia (Genus), coli (Species), is a gram-negative, facultative anaerobic, rod-shaped bacterium, with optimum growing temperatures at 37° C. This bacterium is commonly found in the lower intestines of warm-blooded animals. E. coli makes up about 0.1% of gut flora and most strains are harmless. Some are part of the normal gut flora and help their host by producing vitamin K2 and preventing colonization of the intestine with pathogenic bacteria (CDC, 2014). E. coli makes ATP by aerobic respiration if oxygen is present, but can switch to fermentation or anaerobic respiration if oxygen is limited or absent. The end product of fermentation is lactate, succinate, ethanol, acetate, and carbon dioxide (CDC, 2014; EPA, 2014).

KINGDOM EUBACTERIA: They are unicellular prokaryotes. Most of the bacteria (Germs) that affect your life are members of the Kingdom Eubacteria.

Three bacteria's that live in the human body are Bifidobacterium, Escherichia Coli, and Streptococcus. One of the bacteria's that live in our body is Bifidobacterium longum. This is a multi-faceted extremely friendly bacterium that resides in the digestive tract and helps to keep the whole digestive system running smoothly. B. longum also inhibits the growth of pathogenic bacteria and it produces lactic acid. This can help people who are lactose intolerant. They are believed to be one of the most dominant friendly bacterial species that live inside us, and are early colonizers of the digestive tract of newborn infants. Some health benefits are: stimulation

Bacterium are microorganisms with an extreme importance in the world. Besides the fact that bacteria could have harmful effects, such as food spoilage and causing diseases in both human and animals, it could be exceptionally beneficial also. Bacteria has helped with the advancement of

In “The Germs of Life,” by Lynn Margulis and Emily Case talks about how bacterium has live for about 3.8 billion years because it has been able to adapt in any environment. Therefore, it has been able to live for a long period of time. It goes on saying how not all bacterium is bad there some that benefit us like the bacterial nitrogen fixation help the dirt have nutrients. Furthermore, the cyanobacteria that helps photosynthesis to be able to create the nutriments that are needed for all living things. In addition, bacteria has been taken out from a lot of the things we now used for example, in soaps, creams, mouthwash, and food of course and become antibacterial. People feel safer knowing its antibacterial, but they do not know that bacteria

The principal branches of the tree of life are Bacteria, Archaea, and Eukarya. These three branches distinct and are very much alike to each other. Bacteria and Archaea are comparable in size, shape, generative procedure and amount of chromosomes. Both recreate using binary fission and they only have one chromosome. Bacteria and Archaea both lack a nucleus and other organelles. Eukarya have diversified chromosomes and a nucleus. Archaean cells have dissimilar lipid bonds than both Bacteria and Eukarya. In addition to both Bacteria and Eukarya have greasy acids in their cells but, Archeans do not. Nevertheless all of them have RNA, even though Archaea have more complex RNA polymerases than Bacteria. All three branches on the Tree of Life are

Escherichia coli is a normally harmless gram negative bacteria, commonly found in the digestive system of humans and animals alike. E. coli is a vital part of the digestive tract, but outside the digestive

The main purpose of this essay is to find out if Archaea and Bacteria should be classified as two different Domains or as a single one. As bacteria and archaea both are microscopic and prokaryotic. These two prokaryotes are very abundant on Earth and inhabit a wide spread of areas, also including extreme ones. Both are an example of the most ancient living cells, which have appeared over 3.5 billion years ago. Correct classification of these two organisms is important in order to trace the evolutionary history from the very beginning and make a clearer picture of the common ancestor, if it existed. This work will explain the basic taxonomy principles and compare some of the main similarities and differences between archaea and bacteria. As I understand it, the main difference between the Bacteria and the Eukaryote domains are that eukaryotes have a nucleus and bacteria don 't. I understand that bacteria and archaea have enough of a genetic difference to be separate kingdoms, but why are they separate domains?
