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.
See also: Prokaryotae, Monera, eukaryote.

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

[prōker′ē·ōt]
Etymology: Gk, protos + karyon
a unicellular organism that does not contain a true nucleus surrounded by a double membrane; a bacterium. Division usually occurs through simple fission. Also spelled procaryote. Compare eukaryote. -prokaryotic, adj.

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 .

prokaryote

a unicellular organism lacking a true nucleus and nuclear membrane, having genetic material composed of a single molecule of double-stranded DNA. Prokaryotes with the exception of mycoplasmas have a rigid cell wall. Includes the blue-green algae and bacteria—the Cyanophyceae.
