Document Summary

Super domains: prokaryotes are microscopic single-celled organisms that have neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include bacteria and cyanobacteria eukaryotes are organisms consisting of a cell or cells in which the genetic material is dna in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria. Prokaryotes have all the cellular material: membrane, ribosomes, etc. Some prokaryotes ha(cid:448)e so(cid:373)e sort of (cid:272)apsule, flagellu(cid:373) for (cid:373)o(cid:271)ility, et(cid:272).
