Running head : BENEFITS OF PROKARYOTESBeneficial Impact of Prokaryotes on HumansNameCollegeDateBeneficial Impact of Prokaryotes on Humans all the organisms in this world ar placid of cadres which could either wee-wee a prokaryotic or a eucaryotic var. . All bacterium and some other organisms which belong to the gathering `archaea are unicellular organisms that show prokaryotic novelty (Todar 2000 . All the other organisms (unicellular or multicellular ) on this populace are composed of eucaryotic cells . Since most prokaryotic organisms are bacterium , the two impairment are often employ as synonyms . The differences between prokaryotic cells and eukaryotic cells as identify by Todar (2000 ) are as follows : the prokaryotic cells imbibe no swell defined nucleus . The ancestral cloth at heart a prokaryotic cell ( shown in figure 1 ) is in piddle a circular DNA which is condensed to skeleton a nucleoid , and is not enclosed by a nuclear tissue layer . Eukaryotic cells , on other passel keep back a well defined nucleus which is ring 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 stand for 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 variety of diseases in clement beings , they have also proven multipurpose to the mankind in many ways , in terms of homo race wellness as well in fields of biotechnology , genetic engineering , food and country industry , as described belowFigure 1 . Drawing of a typical prokaryotic cellSource : Haas ,! V (2002 . 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 in force(p) effect of bacteria for humanwellness .

This has led to the introduction of `probitics and pre-biotics . `Probiotics refers to useful , rattling bacteria consumed in small amounts for their potential benefits on health . Pre-biotics refer to original substances which are consumed in to promote the yield of commensal bacteria in the eubstance with the aim of obtaining adjoin d 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 trunk 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 addition 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
