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.
No. The nucleolus is a dense area in the nucleus wherein ribosomes are assembled - but only in (most) eukaryotic cells. Prokaryotic cells do not have a nucleus or any other membrane-bound organelles; their DNA exists as a closed circular loop (a "plasmid") in the cytoplasm.
The nucleoid (meaning nucleus-like) is an irregularly-shaped region within the cell of prokaryoteswhich has nuclear material without a nuclear membrane and where the genetic material is localized. The genome of prokaryotic organisms generally is a circular, double-stranded piece of DNA, of which multiple copies may exist at any time. The length of a genome widely varies, but generally is at least a few million base pairs. Storage of the genome within a nucleoid can be contrasted against that within eukaryotes, where the genome is packed into chromatin and sequestered within a membrane-enclosed organelle called the nucleus.
it is eukaryotic because a prokaryotic doesnt have a nucleus so it couldn't possibly have a nucleolus..
Eukaryotic cells have a nucleus, prokaryotic cells do not.
Just eukaryotic
Ribosomes are made by genes in the nucleolus (which is inside the nucleus) in eukaryotic cells. In prokaryotic cells, the genes are found in the cytoplasm.
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.

AnswerNo, yeast are eukarotic cells.

No, just Eukaryotic.
No, prokaryotic cells do not have mitochondria. Mitochondria are membrane-bound organelles found in eukaryotic cells that play a role in energy production through aerobic respiration. Prokaryotic cells generate energy through processes like glycolysis or fermentation.

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.
