Types of Prokaryotic Cells

Archaea
Archaea

Although Archaea are prokaryotic, they are more closely related to Eukarya and thus cannot be placed within either the Bacteria or Eukarya domains. One property unique to Archaea is the abundant use of ether-linked lipids in their cell membranes.

Cytoplasm
Cytoplasm

The cytoplasm is essentially where nearly all the action happens within a prokaryote - metabolic reactions, and the genetic tasks of replication, transcription, and translation. The following are considered part of the cytoplasm of prokaryotic cells.

Escherichia Coli Bacterium (E Coli)
Escherichia Coli Bacterium (E Coli)

Escherichia Coli The bacteria known as E. coli are examples of the prokaryotic cell type.

Genetic Material (DNA and RNA)
Genetic Material (DNA and RNA)

As opposed to eukaryotic cells, which contain their genetic material inside a nucleus, prokaryotic cells allow their genetic material to float in the cell’s cytoplasm. In fact, prokaryotic cells lack any internal, membrane-bound organelles. While both types of cells use DNA as their primary genetic material, prokaryotes arrange their DNA in a simple circle, as opposed to bundling it into several chromosomes, as eukaryotes do.

Ribosomes
Ribosomes

Prokaryotic vs Eukaryotic Ribosomes The difference between the prokaryotic and eukaryotic organisms is the difference of the location that DNA exists as the name implies (Taylor, 1998). Eukaryotes have a membrane bound nucleus, which contains DNA, but prokaryotes lack a membrane bound nucleus (true nuclei).

Streptococcus Bacterium
Streptococcus Bacterium

Streptococcus is a gram-positive bacteria that causes various illnesses in human bodies. To answer the question briefly, the streptococcus is caused by other streptococcus, wh … ich asexually reproduces by binary fission to get another streptococcus. To answer the question regarding the disease, the disease is simply caused by the bacteria.

Streptomyces Soil Bacteria
Streptomyces Soil Bacteria

Prokaryotes are all single-celled organisms, most of which you know of as bacteria. For example, the famous (or infamous) Escherichia coli bacterium is a prokaryote, as is the streptococcus bacterium responsible for strep throat. The Streptomyces soil bacteria, from which the antibiotic streptomycin is derived, is also a prokaryotic organism.

The Plasma Membrane
The Plasma Membrane

Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
