Bacteria are some of the best examples of prokaryotic organisms. These organisms do not have a membrane-bound nucleus and lack the well-distinguished cell features found in eukaryotes.Know More
Specific examples of prokaryotic organisms include the Escherichia coli bacterium and the Streptococcus bacterium. These are more recognizable as E. coli, a bacteria often found in meat, and the bacteria that causes strep throat.
There is an entire kingdom devoted to prokaryotes, named Archaebacteria. These prokaryotes are ancient forms of bacteria and are notable for living in extreme conditions, such as geothermally active pools and extremely acidic waters. They are considered to be the oldest living organisms on the Earth.Learn more about Biology
Nitrogen is important as organisms need to use it to build important cellular components. However, most organisms are unable to use nitrogen found in the environment because nitrogen is inert. Therefore, nitrogen needs to be fixed or combined with another chemical.Full Answer >
Taxonomy, the science of classifying organisms, is based on phylogeny. Phylogeny attempts to establish the evolutionary history of a species, and taxonomy classifies organisms by this history.Full Answer >
The seven taxa are levels of classification recognized by biologists for placing all living organisms in a unified system of taxonomy. Kingdom, phylum and class are the highest orders of classification, followed by order, family and genus. Species is the lowest common division among organisms.Full Answer >
