Prokaryotic cells are amongst the first organisms to have been on the planet, having existed for almost twice as long as the Animalia in the form of Bacteria, and three times in the form of Archaea.
They are micro-cellular organisms which have no true Nucleus but a mass of free floating DNA in their cytoplasm as well as a complete lack of membrane-bound organelles.
the cell is coated in a capsule of sugar and Murein as well as a cell wall and middlelamella. The membrane contains a mesosome (folding) providing a site for respiration .
Ribosomes are smaller than in Eukaryotic cells with a size of 70S (scovilles) and can have loops of DNA (plasmids) which can be exchanged with other cells to distribute antivirons/antibodies etc
Reproduction is usually Asexual and Binary fission

What are the 4 components that all prokaryotic cells have?
External structures of a prokaryotic cell include glycocalyces, flagella, fimbriae, and pili. Most prokaryotic cells have a cell wall. Prokaryotic cells have a cytoplasmic membrane, cytosol, and inclusions. The nonmembranous organelles found in a prokaryotic cell are ribosomes and the cytoskeleton.
What is the main ring of DNA in a prokaryotic cell?
The main ring of DNA in a prokaryotic cell is called the bacterial chromosome or nucleoid. It contains the majority of the organism's genetic material and is responsible for controlling cellular functions and replication.
What are some characteristics of the prokaryote cell?
Prokaryotic cell differ from eukaryotic cell in that they lack a nucleus and membranous organelles. Now the main features inside a prokaryotic cell are: * cytoplasm * ribosomes * Plasmid * Nucleoid (circular DNA) And Features outside the prokaryotic cell are: * Capsule * Pili (hair like structures on surface of capsule * Flagellum ( tail like structure)
Which organelle of a prokaryotic cell contains genetic information?
The genetic information in a prokaryotic cell is typically found within the nucleoid region, which is a centralized area that contains the cell's DNA. Prokaryotic cells lack a true membrane-bound nucleus, so the nucleoid serves as the main site for genetic material storage and replication.
In a eukaryotic cell what is one of the structures in the nucleus that is made up of DNA and protein in a prokaryotic cell is the main ring of DNA?
In a eukaryotic cell, the structure made up of DNA and proteins in the nucleus is the chromosome. In prokaryotic cells, the main ring of DNA is called the nucleoid, which lacks a membrane-bound nucleus.

Process by which zygote becomes a mature individual through repeated cell divisionand cell difference?
The main differences between cell division in prokaryotic. An organism know to become two cells, then four cells, and so on.
What is the main difference between a prokaryotic and eukaryotic cell?
the main difference is that the prokaryotic cell lacks definite nucleus while a eukaryotic cell contains a well defined nucleus with double membrane.besides prokaryotic cell also lacks membrane bounded organelles while a eukaryotic cell contains all membrane bounded organelles like mitochondria,endoplasmic reticulum etc
What is the main ring of DNA in a prokaryotic cell?
The main ring of DNA in a prokaryotic cell is called the bacterial chromosome or nucleoid. It contains the majority of the organism's genetic material and is responsible for controlling cellular functions and replication.
What kinds of cell does not have a nucleus?
There are two main types of cells, prokaryotic and eukaryotic. Prokaryotic cells do not contain a nucleus, these feature cells such as bacteria,archaea, and protists. To be more specific, prokaryotic cells do not have a membrane around their genetic material.
What are the two main types of cells that make up all living organisms?
prokaryotic, and eukaryotic (with and without a nucleus)
What 3 main cell parts do prokaryotic and eukariyotic have in comin?
There are severl comparments.Some are cell membrane,cell wall,ribosomes,cytoplasm etc
What is the biological term for a cell?
A cell is a cellThere are two main types, Prokaryotic cells and Eukaryotic cells but they are still cells...!
In a prokaryotic cell the chromosomes are located in a main ring of?
In a prokaryotic cell, the chromosomes are located in a main ring of DNA known as the nucleoid. The nucleoid is not enclosed within a membrane-bound nucleus, unlike in eukaryotic cells. It contains the genetic material necessary for the cell's function and reproduction.
What are some characteristics of the prokaryote cell?
Prokaryotic cell differ from eukaryotic cell in that they lack a nucleus and membranous organelles. Now the main features inside a prokaryotic cell are: * cytoplasm * ribosomes * Plasmid * Nucleoid (circular DNA) And Features outside the prokaryotic cell are: * Capsule * Pili (hair like structures on surface of capsule * Flagellum ( tail like structure)

In a eukaryotic cell what is one of the structures in the nucleus that is made up of DNA and protein in a prokaryotic cell is the main ring of DNA?
In a eukaryotic cell, the structure made up of DNA and proteins in the nucleus is the chromosome. In prokaryotic cells, the main ring of DNA is called the nucleoid, which lacks a membrane-bound nucleus.
