Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. Bacterial cells are very small, roughly the size of an animal mitochondrion (about 1-2µm in diameter and 10 µm long). Prokaryotic cells feature three major shapes: rod shaped, spherical, and spiral. Instead of going through elaborate replication processes like eukaryotes, bacterial cells divide by binary fission.

Bacteria perform many important functions on earth. They serve as decomposers, agents of fermentation, and play an important role in our own digestive system. Also, bacteria are involved in many nutrient cycles such as the nitrogen cycle, which restores nitrate into the soil for plants. Unlike eukaryotic cells that depend on oxygen for their metabolism, prokaryotic cells enjoy a diverse array of metabolic functions. For example, some bacteria use sulfur instead of oxygen in their metabolism.

Bacteria and Archaea are two types of prokaryotes. More specifically, from bacteria organisms like Escherichia coli (E. Coli) and from archaea, Caldisphaera lagunensis.
Some examples of prokaryotic organisms are cyanobacteria, staphylococcus aureus, and E.Coli. Some more examples are lactobacillus and salmonella.
Bacteria and viruses are examples of prokaryotic organisms.
There are so many prokariyotes.Every bacteria and arche bacteria are examples.

A spirochete (also spelt as Spirochaete) is Prokaryotic.
Yeast, Halobacteria and Aeropyrum pernix are three prokaryotic organisms.
Prokaryotic cells do not have a nucleus and are considered to be the simplest of all cell forms. Some examples include the E. coli, salmonella and the bacillus.
These single celled organisms are called prokaryotes.
