The only organisms with prokaryotic cells belong to the domains Bacteria and Archaea. These organisms are considered to be prokaryotes, which are characterized by being cells that do not possess a distinct nucleus.
Prokaryotic cells are single cells that evolved before eukaryotes, which are organisms whose cells contain nuclei and organelles. A prokaryotic cell has no true nucleus or membrane-bound structures called organelles. Pro...
Prokaryotic cells do not have a true nucleus. The word "prokaryotic" means "before nucleus." Eukaryotic cells, on the other hand, came after the prokaryotes and contain structures not present in prokaryotic cells.
Another name for prokaryotic cells is prokaryotes, simple life forms that consist of the kingdoms of Monera and Archaea. Prokaryotic is Greek for "before nucleus."
Archaea lack a cell nucleus and other organelles with membranes, so they are prokaryotic. They were originally believed to be a type of bacteria, the other major group of prokaryotes.
Bacteria are prokaryotic cells, which are characterized by a lack of a membrane-bound nucleus. They are typically simpler than eukaryotic cells, which have a membrane-bound nucleus and organelles responsible for cell fun...
Eukaryotic cells differ from prokaryotic cells in a number of ways, notably in size, complexity and cooperative behavior. The division between eukaryotes and prokaryotes is the deepest divide in nature, with two domains ...
