Eukaryotes possess linear chromosomes, a membrane-bound nucleus and complex organelles. Prokaryotes possess a circular chromosome and lack the sophisticated organelles and nucleus present in eukaryotes. It is important to note that all multicellular organisms are eukaryotes, though not all eukaryotes are multicellular. As members of this kingdom, people are generally very familiar with the animal kingdom.
