Prokaryotes that exhibit magnetotaxis, collectively known as the magnetotactic bacteria, are those whose direction of motility is influenced by the Earth’s geomagnetic and ... A prokaryote is a single-celled organism that lacks a nucleus and other membrane-bound organelles. The word prokaryote comes from the Greek πρό (pro, 'before') and κάρυον (karyon, 'nut' or 'kernel'). In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota. But in the three-domain system, based upon molecular analysis, pr…
