en.wikipedia.org/wiki/Prokaryote

A prokaryote is a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle. The word prokaryote comes from the Greek πρό (pro) "before" and κάρυον (karyon) "nut or kernel". Prokaryotes are divided into two domains, Archaea and Bacteria.Species with nuclei and organelles are placed in the third domain, Eukaryota.

Prokaryotic cells do not have a separate area inside them enclosed in a casing to hold genetic material. Instead, the nuclear body within a prokaryotic cell, called a nucleoid, usually contains one circular chromosome consisting of DNA. Prokaryotic cells do not have a dense spherical structure called a nucleolus that contains the nucleus.

Prokaryotic cells are not as complex as eukaryotic cells. They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid. Prokaryotic organisms have varying cell shapes.

Prokaryotic cells are very small (an average bacterial cell is around 8 micrometres long). These cells do not have any membrane-bound organelles such as mitochondria. Prokaryotic cells may have a cell wall but, it is not made of cellulose. These cells may contain extra DNA in structures called plasmids.

The distinction between prokaryotes and eukaryotes is considered to be the most important distinction among groups of organisms. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of ...

Prokaryotic Cells Prokaryotic cells are the simplest systems that exhibit all of the signs of life. They are the smallest types of cell, averaging 2-5 µm in length, which makes them just visible under the light microscope.

The Prokaryotic Cell. Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

Prokaryote: Prokaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes. The prokaryotic cell membrane is made up
