Prokaryotes are a group of organisms that lack a membrane bound nucleus. Most prokaryotes are unicellular and are divided into two groups; bacteria and archaea. The word prokaryote comes from the Greek πρό- (pro-) "before" + καρυόν (karyon) " or nutkernel." The defining characteristic is the absence of a nucleus.
The genomes of prokaryotes are held within an irregular DNA/protein complex in the cytosol called the nucleoid, which lacks a nuclear envelope. Prokaryotes generally lack membrane-bound cell compartments: such as mitochondria and chloroplasts. Instead processes such as oxidative phosphorylation and photosynthesis take place across the prokaryotic plasma membrane. However, prokaryotes do possess some internal structures, such as cytoskeletons, and the bacterial order Planctomycetes have a membrane around their nucleoid and contain other membrane-bound cellular structures. Both eukaryotes and prokaryotes contain large RNA/protein structures called ribosomes, which produce protein. Prokaryotes are usually much smaller than eukaryotic cells.
Prokaryotes also differ from eukaryotes in that they contain only a single loop of stable chromosomal DNA stored in an area named the nucleoid, while eukaryote DNA is found on tightly bound and organized chromosomes. Although some eukaryotes have satellite DNA structures called plasmids, these are generally regarded as a prokaryote feature, and many important genes in prokaryotes are stored on plasmids. Prokaryotes have a larger surface area to volume ratio giving them a higher metabolic rate, a higher growth rate and consequently a shorter generation time compared to Eukaryotes.
What else can I help you with?
Is the nuclear envelope in prokaryotic or eukaryotic cells?
The nuclear envelope is found in eukaryotic cells, not in prokaryotic cells.
Is the plasmid found in prokaryotic or eukaryotic cells?
The plasmid is found in prokaryotic cells.
Is the plasma membrane of cells prokaryotic or eukaryotic?
The plasma membrane of cells is found in both prokaryotic and eukaryotic cells.
Is circular DNA found in prokaryotic or eukaryotic cells?
Circular DNA is typically found in prokaryotic cells, such as bacteria, rather than in eukaryotic cells.
What is the differences between prokaryotic and eukaryotic?
Prokaryotic cells lack a membrane-bound nucleus and organelles, while eukaryotic cells have both a nucleus and organelles enclosed in membranes. Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells. Eukaryotic cells are found in plants, animals, fungi, and protists, whereas prokaryotic cells are found in bacteria and archaea.

lysosomes are found in eukaryotic cells.
Is the plasma membrane of cells prokaryotic or eukaryotic?

Circular DNA is typically found in prokaryotic cells, such as bacteria, rather than in eukaryotic cells.
Is a nucleus found in the eukaryotic and prokaryotic cells?
No, just Eukaryotic.

What is the difference between something eukaryotic and something prokaryotic?
There are quite a few differences between eukaryotic and prokaryotic cells. Prokaryotic cells do not have a nucleus, while eukaryotic cells do. Prokaryotic cells are not found in humans while eukaryotic cells are. Prokaryotic cells are primitive while eukaryotic cells are much more evolved.
What are the two major types of cells?
The two major types of cells are prokaryotic cells, which lack a nucleus and membrane-bound organelles, and eukaryotic cells, which have a nucleus and membrane-bound organelles. Eukaryotic cells are found in plants, animals, fungi, and protists, while prokaryotic cells are found in bacteria and archaea.
What can be found in prokaryotic and eukaryotic cells?
DNA
Do people have prokaryotic or eukaryotic cells?
The cells found in the human body are eukaryotic cells. Organisms that have eukaryotic cells are usually multicellular like humans. Organisms that have prokaryotic cells are usually unicelluar, like bacteria.
