Answer:
In Bacteria and Archaea, the cells don't contain a nucleus. These groups have different Ribosomal RNAs (rRNAs). Moreover, Bacteria and Archaea have different cell walls (with peptidoglycans in Bacteria)
In Eukarya, the cells have a nucleus.
The prokaryotes play important ecological roles, these organisms help to synthesize vitamins in the digestive system of animals and they are required for the fermentation process
The horizontal gene transfer is the transmission of genetic information between no related species. In prokaryotes, the process of horizontal gene transfer is given by the use of DNA fragments derived from plasmids to integrate them into their genomes. In eukaryotes, the horizontal gene transference is a less common process
halophile: organisms that live in salt
extremophile: organisms that live in extreme conditions
thermophile: organisms that live in high temperature
methanogen: organisms that produce methane
decomposer: organisms that decompose organic compounds
nitrogen fixation: that fix nitrogen in organic compounds
aerobic: that survive in oxygen conditions
anaerobic: that survive without oxygen
photoautotroph: that produce food using light
photoheterotroph: that use light for energy
chemoautotroph: that produce food using chemical compounds
chemoheterotroph: that use chemical compounds for energy
transformation, transduction and conjugation are gentic processes in bacteria
binary fission: asexual reproduction in archaea and bacteria
mutualism, commensalism, parasitism are ecological relationships among populations
