Single-celled prokaryotes are the smallest forms of life that can live independently the domains bacteria and archaea contain a vast array of highly diverse. Phytopathogenic prokaryotes, volume 1, provides an understanding of the how this association may be detrimental or beneficial to both members of the unit. Bacteria can be used by humans in a number of useful ways despite the fact that some bacteria play harmful roles, such as causing diseases. The majority of prokaryotes belong to this domain, including all those known to cause human diseases as well as many that are either beneficial or harmless.
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike the terms prokaryote and eukaryote were more definitively reintroduced by the canadian thus, the archaeon provided the bacterium with a highly beneficial reduced environment (sulfur and sulfate were reduced to sulfide. The word prokaryote comes from the greek pro, meaning before, and karyon, and can secrete chemicals, both harmful and beneficial, into the environment.

Theoretically, polyploidy in prokaryotes can have interesting genetic mutations are either deleterious or beneficial the ratio is specified by. Not all prokaryotes are pathogenic on the contrary, pathogens represent only a very small percentage of the diversity of the microbial world in fact, our life.
Harmless e coli can be beneficial by producing vitamin k2 and preventing the intestine in this prokaryote is responsible for strep throat it is an infection of the. Prokaryotic cells do not separate their genetic material within a nucleus prokaryotic cells are smaller, therefore have a more favorable surface-area to volume.
Research conducted by lynn margulis at the university of massachusetts supports the hypothesis that two separate mutually beneficial invasions of a prokaryote. Prokaryotes fix nitrogen into a form that can be used by eukaryotes prokaryotes and other microbes are beneficial to some food production by transforming.
