Prokaryotic Meaning and Definition in Wikipedia

Prokaryotes (or monera) are the simplest living things:

Prokaryotes are cells which do not have a cell nucleus, and lack other things eukaryotes (cells with a true nucleus) have. Prokaryotes do not have membranes inside the cell. This means that there are no vacuoles, Golgi apparatus, endoplasmic reticula or other organelles inside the cell. However, they do have ribosomes, though of a simpler kind than eukaryotes. Eukaryote cells include organelles which were once free-living prokaryotes.

In 1977, Carl Woese proposed dividing prokaryotes into the Bacteria and Archaea (originally Eubacteria and Archaebacteria) because of the major differences in the structure and genetics between the two groups of organisms. This arrangement of Eukaryota (also called "Eukarya"), Bacteria, and Archaea is called the three-domain system, replacing the traditional two-empire system.
