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.

pro·kar·y·ote

(prō-kar'ē-ōt),
A member of the superkingdom Prokaryotae; an organismic unit consisting of a single and presumably primitive moneran cell, or a precellular organism, which lacks a nuclear membrane, paired organized chromosomes, a mitotic mechanism for cell division, microtubules, and mitochondria.

procaryote

(prō-kăr′ē-ōt′)
n.
Any of various microorganisms of the domains Archaea and Bacteria, characterized by the absence of a distinct membrane-bound nucleus and membrane-bound organelles and by the simultaneous occurrence of DNA transcription and protein synthesis at the same site, in contrast to eukaryotes. Also called moneran.

prokaryote

or

prokaryote

any organism, including those in the domains BACTERIA or ARCHAEA, that lacks a membrane-bound nucleus and has no MITOSIS or MEIOSIS. Organelles such as the MITOCHONDRION and the ENDOPLASMIC RETICULUM are also lacking. Compare EUKARYOTE and See Fig. 155 .
