prokaryote

 [pro-kar´e-ōt]
any member of the kingdom Monera; a unicellular organism lacking a true nucleus and nuclear membrane, having genetic material composed of a single loop of naked double-stranded DNA. The microorganisms, comprising the bacteria and blue-green bacteria (formerly blue-green algae), are predominantly unicellular but may have filamentous, mycelial, or colonial forms. Prokaryotes, with the exception of genus Mycoplasma, have a rigid cell wall. adj., adj prokaryot´ic.
