A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus. 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, prokaryotes are. Prokaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes
Universal features of cells. Characteristics of prokaryotic cells. Surface area-to-volume ratio Prokaryote definition is - any of the typically unicellular microorganisms that lack a distinct nucleus and membrane-bound organelles and that are classified as a kingdom (Prokaryotae synonym Monera) or into two domains (Bacteria and Archaea)
Prokaryote Definition. Prokaryotes are unicellular organisms that consist of a single prokaryotic cell.Prokaryotic cells are simple cells that do not have a true nucleus or other cell organelles. Bacteria and Archaea are the two domains of life that are prokaryotes. Prokaryotes can be contrasted with eukaryotes, which have more complex eukaryotic cells with a nucleus and organelles Prokaryote This set of characteristics is distinct from eukaryotes (also spelled eucaryotes), organisms that have cell nuclei and may be variously unicellular or multicellular Prokaryote species may be free-living or exist in pathogenic or mutualistic associations with hosts, either intra- or extracellular. They may exhibit aerobic or anaerobic metabolisms, and many acquire their energy from chemical sources that are toxic to other living things prokaryote (plural prokaryotes) An organism whose cell (or cells) are characterized by the absence of a nucleus or any other membrane - bound organelles . In the two-empire system of biological taxonomy , an organism of the kingdom Prokaryotae (now superseded)

On a prokaryote, the DNA tends to be circular. It can be all flipped around and whatever else but at the end of the day, it would be circular DNA. So those are the three core distinctions: nuclear membrane, other membrane-bound organelles, like mitochondria and the Golgi apparatus, and then you also have multiple single strands of DNA versus circular DNA Prokaryote refers to any of the group of organisms primarily characterized by the lack of true nucleus and other membrane-bound cell compartments: such as mitochondria and chloroplasts, and by the possession of a single loop of stable chromosomal DNA in the nucleiod region and cytoplasmic structures, such as plasma membrane, vacuoles, primitive cytoskeleton, and ribosomes
A prokaryote is a simple, single-celled (unicellular) organism that lacks an organized nucleus or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes.

(Chatton, 1925). Since then the term, when paired with its dichotomous counterpart 'eukaryote', has formed the fundamental basis for classification in biology Prokaryote.

prokaryote A single-celled organism in which the cell lacks a true nucleus and the DNA is present as a loop in the cytoplasm rather than as chromosomes bounded by a nuclear membrane. The prokaryotes comprise the bacteria, which appear in the fossil record more than 3000 Ma ago and are the oldest forms of life known, and the cyanobacteria, known from slightly younger rocks This Amoeba Sisters video starts with providing examples of prokaryotes and eukaryotes before comparing and contrasting prokaryotic cells with eukaryotic cel.. prokaryote.
