Diagram of a prokaryotic cell, a bacterium with a flagellum. A prokaryote (/ p r oʊ ˈ k ær i oʊ t,-ə t /; less commonly spelled procaryote) [1] is a single-celled organism whose cell lacks a nucleus and other membrane-bound organelles. [2]

Much of gene structure is broadly similar between eukaryotes and prokaryotes. These common elements largely result from the shared ancestry of cellular life in organisms over 2 billion years ago. [3] Key differences in gene structure between eukaryotes and prokaryotes reflect their divergent transcription and translation machinery.

The metabolism of prokaryotes is far more varied than that of eukaryotes, leading to many highly distinct prokaryotic types. For example, in addition to using photosynthesis or organic compounds for energy, as eukaryotes do, marine prokaryotes may obtain energy from inorganic compounds such as hydrogen sulfide .
Original – A diagram of the Prokaryotic Bacteria cell, showing its parts, which is the Pilus, Cytoplasm, Ribosomes, Nucleoid (DNA), Plasma membrane, Cell wall, Capsule, and the Flagellum. Reason It has a high educational value, as it shows the parts of a Prokaryote cell.
Details of the relation of Asgard members and eukaryotes are still under consideration, [103] although, in January 2020, scientists reported that Candidatus Prometheoarchaeum syntrophicum, a type of Asgard archaea, may be a possible link between simple prokaryotic and complex eukaryotic microorganisms about two billion years ago.
Prokaryotes are not as structurally complex as eukaryotes, and were once thought to have little internal organization, and lack cellular compartments and internal membranes; but slowly, details are emerging about prokaryotic internal structures that overturn these assumptions. [2]
