Prokaryotic cells are simpler than eukaryotic cells, and an organism that is a prokaryote is unicellular; it is made up of only one prokaryotic cell. Prokaryotic cells are usually between 0.1 to 5 micrometers in length (.00001 to .0005 cm). Eukaryotic cells are generally much larger, between 10 and 100 micrometers.
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).
Prokaryotic cells lack organelles found in eukaryoitic cells such as mitochondria, endoplasmic reticuli, and Golgi complexes. According to the Endosymbiotic Theory , eukaryotic organelles are thought to have evolved from prokaryotic cells living in endosymbiotic relationships with one another.
prokaryotic cell: The form of cell composing many primitive unicellular organisms, such as bacteria. Prokaryotic cells do not have nuclei, which are partitioned by an intracellular membrane; instead the DNA forms one main coil in the cell cytoplasm. See also: cell
Prokaryote definition, any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

Prokaryotic cells are less organized than eukaryotic cells. There are also differences in the levels of regulation, such as cell growth, in prokaryotes. You can see this in the mutation rates of bacteria because fewer regulations allow for rapid mutations and multiplication.
Eukaryotic cells are larger and more complex than prokaryotic cells, which are found in Archaea and Bacteria, the other two domains of life. Characteristics of Eukaryotic Cells. Eukaryotic cells contain a variety of structures called organelles, which perform various functions within the cell.
