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

∙ 13y agoA prokaryotic cell does not merely lack a nucleus (contrary to popular belief) but rather does not have a membrane-enclosednucleus. It also lacks membrane-enclosed organelles. Basically all organelles and nucleic material float freely in the cytoplasm.

∙ 10y ago1.Prokaryotic cells don't have a nucleus
2. Procaryotic cells have a call wall which consists of murein (or pseudomurein in case of archea)
3. They don't have mitochondria, chloroplasts, golgi aparatus, ER. they lack organells in general.
4. They multiply by a process different from mitosis or meiosis.

Next they lack a nucleus and therefore the nuclear membrane.

What is the main ring of DNA in a prokaryotic cell?
Chromosomes
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)
Is the cell membrane the main difference between prokaryotes and eukaryotes?
No - although they differ slightly, both prokaryotic and eukaryotic cells have a cell membrane. The main difference is that eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotic cells have neither of these.
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?
the chromosome
How does the storage of the DNA of a prokaryotic cell differ from that of a eukaryotic cell?
In a eukaryotic cell DNA is stored in a nucleus as chromatin ( unless the cell is in the process of mitosis in which the DNA would arrange itself as chromosomes) However a prokaryotic cell has no nucleus, the genetic material is stored in the cytoplasm of the cell, prokaryotic cells also have a plasmid which is a ring of DNA which is separate to the main genetic material. This plasmid contains DNA not found in the main genetic material. The plasmid is also in the cytoplasm.
What is the main ring of DNA in a prokaryotic cell?
Chromosomes
In a prokaryotic cell the chromosomes are located in a main ring of?
Mitosis

What are the two main types of organisms?
prokaryotic cell, binary fission
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 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...!
Is the cell membrane the main difference between prokaryotes and eukaryotes?
No - although they differ slightly, both prokaryotic and eukaryotic cells have a cell membrane. The main difference is that eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotic cells have neither of these.
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?
