New Classification(Branching System) They are classify organisms into Three domains(are the cell types that organism has) 1-Archaea domain 2-Bacteria domain 3-Eukarya domain . Each domain sub divided into kingdoms followed by phyla , class , order , family, genus and species . we will focus on domain and kingdom : 1-Domain Bacteria :Includes organisms commonly referred to as bacteria which are unicellular prokaryotes ,they are tiny organisms that reproduce a sexually ,for example(the common bacteria that make us sick and blue-green algae(cyanobacteria). This domain has just one kingdom :bacteria). 2-Domain Archaea : primitive bacteria that live in the harsh environments, specialized group of unicellular prokaryotes(ancient bacteria) ,scientists, discovered these unique organisms(extremophiles) living in areas of extreme conditions some archaea found in hot spring and are called thermophiles(heat loving) other founds in very salt conditions called halophiles(salt loving) or low pH . This domain has just one kingdom archaea . 3- Domain Eukarya : Includes all eukaryotes ,has four kingdoms :animalia , Plantae, Protista and fungi .They are classified based on the complexity of their cellular organization, their ability to obtain nutrients, and their mode of reproduction. Why do scientists classify organism important because: It is impossible to study every living organism from an individual level. Therefore, classification is necessary to facilitate easy study of organisms.
