Running head : BENEFITS OF PROKARYOTESBeneficial Impact of Prokaryotes on HumansNameCollegeDateBeneficial Impact of Prokaryotes on Humans all the organisms in this world ar dispassionate of cadres which could either wee-wee a prokaryotic or a eucaryotic var. . All bacterium and some other organisms which get to the gathering `archaea are unicellular organisms that show prokaryotic physical be (Todar 2000 . All the other organisms (unicellular or multicellular ) on this nation are composed of eucaryotic cells . Since most prokaryotic organisms are bacterium , the two basis are often apply as synonyms . The differences between prokaryotic cells and eukaryotic cells as place by Todar (2000 ) are as follows : the prokaryotic cells pitch no swell defined nucleus . The ancestral secular intimate a prokaryotic cell (sh own in figure 1 ) is in piddle a circular DNA which is condensed to system a nucleoid , and is not enclosed by a nuclear tissue layer . Eukaryotic cells , on other kick in catch a well defined nucleus which is encircled by a nuclear membrane and contains genetic material in form of chromosomes . Other membrane bound cytoplasmatic organelles like mitochondria , lysosomes , golgi frame-up etc which are normally vex in a eukaryotic cell are not present inside a prokaryotic cell . Prokaryotic cells contain a cell wall which is not present in eukaryotic fleshly cells (may be present in eukaryotic plant cells . though prokaryotic organisms , typically bacterium have been largely affect as the causative agent of classification of diseases in clement beings , they have also proven utile to the mankind in many ways , in terms of clement race wellness as well in fields of biotechnology , genetic engineering , food and agricultural industry , as described belowFigure 1 .

Todar s online textbook of bacteriology Retrieved on 30 /03 /07 from http /textbookofbacteriology .net /structure .htmlBenefits Provided by Prokaryotes to Human HealthThere has been increasing awareness regarding the dear effect of bacteria for human health .

This has led to the introduction of `probitics and pre-biotics . `Probiotics refers to useful , experience bacteria consumed in small amounts for their potential benefits on health . Pre-biotics refer to original substances which are consumed in to promote the emergence of commensal bacteria in the eubstance with the aim of obtaining adjoind benefits on human health (Canfield , 2006 . In the United States , the probiotic bacteria are unconnected in form of conventional dairy foods supplemented with these bacteria or as dietary supplements in the form of capsules , powder or tablets (Sanders , 2000Improving Body s ImmunityOur bodies are inhabited by billions and trillions of harmless bacteria also known ascommensals . These harmless bacteria prevent the system against invasion by the pathogenic bacteria . Use of pro-biotic substances appears to be useful in cases where there is disruption of colonizing microorganisms in the body due to old age , treatment with antibiotics immuno-suppression or to plus the immunity of the body against antibiotic resistant pathogens . Since the prokaryotes present in probiotics help in bolstering the intestinal immunity , they may be helpful in fighting against...If you want to get a full essay, order it on our website: OrderCustomPaper.com< br/>
