Running head : BENEFITS OF PROKARYOTESBeneficial Impact of Prokaryotes on HumansNameCollegeDateBeneficial Impact of Prokaryotes on Humans all the organisms in this world ar sedate of cadres which could either wee-wee a prokaryotic or a eucaryotic var. . All bacterium and some other organisms which comprise to the gathering `archaea be unicellular organisms that show prokaryotic contour (Todar 2000 . All the other organisms (unicellular or multicellular ) on this acres are composed of eucaryotic cells . Since most prokaryotic organisms are bacterium , the two ground are often use as synonyms . The differences between prokaryotic cells and eukaryotic cells as bring up by Todar (2000 ) are as follows : the prokaryotic cells puddle no swell defined nucleus . The ancestral strong deep down a prokaryotic cell (shown in figure 1 ) is in piddle a circular DNA which is condensed to cause a nucleoid , and is not enclosed by a atomic tissue layer . Eukaryotic cells , on other communicate subscribe to a well defined nucleus which is touch 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 fork out 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 mixture of diseases in clement beings , they have also proven utilitarian to the mankind in many ways , in terms of gentleman race wellness as well in fields of biotechnology , genetic engineering , food and pastoral industry , as described belowFigure 1 .

This has led to the introduction of `probitics and pre-biotics . `Probiotics refers to useful , live bacteria consumed in small amounts for their potential benefits on health . Pre-biotics refer to original substances which are consumed in to promote the egression 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 free-swimming 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 remains 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 remains due to old age , treatment with antibiotics immuno-suppression or to maturation 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
