List at least two ways that prokaryotic cell division is similar to eukaryotic cell division?
- Both have DNA as their genetic material (it's DNA that tells cells what kind of cells they should be).
- Both are covered by a cell membrane.
- Both contain RNA.
- Both are made from the same basic chemicals: carbohydrates, proteins, nucleic acid, minerals, fats and vitamins.
- Both have ribosomes (the structures on which proteins are made).
- Both regulate the flow of the nutrients and wastes that enter and leave them.
- Both have similar basic metabolism (life processes) like photosynthesis and reproduction.
- Both require a supply of energy.
- Both are highly regulated by elaborate sensing systems ("chemical noses") that make them aware of the reactions within them and the environment around them.
That's what prokaryotic and eukaryotic cells have in common. But there are significant differences between them too. The two main differences are age and structure.(:

What else can I help you with?
Is the evolution of the prokaryote before a eukaryote cell?
Yes, prokaryotic cells evolved before eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both. It is believed that eukaryotic cells evolved from prokaryotic cells through a process called endosymbiosis.
Are humans cells prokaryotic or eukaryotic explain?
human bones are eukaryotic cells as they contain well developed nucles.
Where protist were the first prokaryotic organisms on Earth?
The oldest life fossils are very simple - prokaryotic no doubt and not that different from many of today's prokaryotic cell structure. Evolution in general seems to be an increase in complexity. Thus the first cells would logically be prokaryotic, or at least noneukaryotic. This is because prokaryotic cells are much simpler than prokaryotic cells which contain multiple membranous organelles to complicate their structure. Note that just because the oldest life fossils are prokaryotic does not prove that they preceeded the eukaryotes or that they were the VERY FIRST life on earth. Can there be simpler life than prokaryotes one wonders? However, no fossils have been found that are older than those 'first' prokaryotes, and as I have said it would be illogical for more complex eukaryotes to precede the simpler prokaryotes. The oldest fossils therefore (between 3.5 and 3.8 billion years old) are thus accepted as both the first life and prokaryotic.
What does not have organelles?
Prokaryotic cells, such as bacteria, do not have membrane-bound organelles found in eukaryotic cells. Prokaryotic cells have a simpler structure with a lack of organelles such as a nucleus, mitochondria, and endoplasmic reticulum. They typically have a single circular chromosome and lack membrane-bound organelles.
Is nucleolus found in prokaryotic and eukaryotic cells?
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.

Are potato cells prokaryotic or euyarotic?
Eukaryotic. Plantae is a kingdom under the domain Eukarya.
Which types of cell is the least complex and usually does not contain a nucleus or the other organelles?
a prokaryotic cell
What kingdom has the least amount of species?
The kingdom with the least amount of species is the kingdom Monera, which consists of unicellular prokaryotic organisms such as bacteria and archaea.
How do you find the least common factor in division?
The least common factor is always 1.
How do you calculate least count for traveling microscope?
to calculate the least count of travelling microscope first see the no. of division on the main scale say between 12 and 13 there are 20 divisions and the no.of division on vernier scale is 50 then 1 msd = 20 division 1 division = 1/20 msd=0.05 1vsd = 50 division least count = msd/vsd =0.05/50=0.001 so least count is 0.001 cm
How you calcuate micrometer least count?
least count of a micrometer= pitch/no of division on the circular scale
Where could one find a reliable free ebooker?
Ebookers is the European division of Orbitz. Travelocity, Expedia, Priceline, Hotwire, TripAdvisor and ChoiceHotels are several similar websites. They should all at least be free to browse.

Prokaryotic cells have a simpler structure with a lack of organelles such as a nucleus, mitochondria, and endoplasmic reticulum. They typically have a single circular chromosome and lack membrane-bound organelles.
How do nurses use polynomial division?
They don't. At least, not for their nursing work.
