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 depart to the gathering `archaea argon unicellular organisms that show prokaryotic var. (Todar 2000 . All the other organisms (unicellular or multicellular ) on this kingdom are composed of eucaryotic cells . Since most prokaryotic organisms are bacterium , the two terms are often use as synonyms . The differences between prokaryotic cells and eukaryotic cells as picture by Todar (2000 ) are as follows : the prokaryotic cells devote no swell defined nucleus . The ancestral real(a) indoors a prokaryotic cell (shown in figu re 1 ) is in piddle a circular DNA which is condensed to family a nucleoid , and is not enclosed by a atomic tissue layer . Eukaryotic cells , on other trade kibosh a well defined nucleus which is skirt by a nuclear membrane and contains genetic material in form of chromosomes . Other membrane bound cytoplasmic organelles like mitochondria , lysosomes , golgi frame-up etc which are normally leave 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 renewal of diseases in clement beings , they have also proven utilitarian to the mankind in many ways , in terms of human race race wellness as well in fields of biotechnology , genetic engineering , food and rustic industry , as described belowFigure 1 .

This has led to the introduction of `probitics and pre-biotics . `Probiotics refers to useful , stomach bacteria consumed in small amounts for their potential benefits on health . Pre-biotics refer to original substances which are consumed in to promote the outgrowth of commensal bacteria in the eubstance with the aim of obtaining adjoind benefits on hu man 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 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 corpse due to old age , treatment with antibiotics immuno-suppression or to summation 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
