what are some differences between prokaryotes and eukaryotes?

Answer 1

instead of copying wikipedia, i'll make it very easy
prokaryotes lack organelles...this means nucleus, ER, lysosomes, etc etc etc....they have NO internal membranes .....eukaryotes have organelles/internal membranes

prokaryotes have circular DNA....it is still twisted, but it is a circle and prokaryote DNA has none of the proteins called HISTONES that are present in eukaryotes. in eukaryotes the DNA wraps around the histones.

those are the main differences that an intro course would require...those are even sufficient for my AP course

Answer 2

Prokaryotes are very distinct from eukaryotes (meaning true kernel, also spelled "eucaryotes") because eukaryotes have true nuclei containing their DNA, while prokaryotes' genetic material is not membrane-bound. Eukaryotes are organisms that have cell nuclei and may be variously unicellular or multicellular. An example of an eukaryote would be a human. The difference between the structure of prokaryotes and eukaryotes is so great that it is considered to be the most important distinction among groups of organisms. Most prokaryotes are bacteria, and the two terms are often treated as synonyms. In 1977, Carl Woese proposed dividing prokaryotes into the Bacteria and Archaea (originally Eubacteria and Archaebacteria) because of the significant genetic differences between the two. This arrangement of Eukaryota (also called "Eukarya"), Bacteria, and Archaea is called the three-domain system replacing the traditional two-empire system.

The cell structure of prokaryotes differs greatly from eukaryotes in many ways. The defining characteristic is the absence of a nucleus or nuclear envelope. Prokaryotes also were previously considered to lack cytoskeletons and do lack membrane-bound cell compartments such as vacuoles, endoplasmic reticulum/endoplasmic reticula, Golgi apparatus, mitochondria, and chloroplasts. In eukaryotes, the latter two perform various metabolic processes and are believed to have been derived from endosymbiotic bacteria. In prokaryotes similar processes occur across the cell membrane; endosymbionts are extremely rare. Prokaryotes also have cell walls, while some eukaryotes, particularly animals, do not. Both eukaryotes and prokaryotes have structures called ribosomes, which produce protein. Prokaryotes are usually much smaller than eukaryotic cells.

Taking into account membrane bound organelles, prokaryotes also differ from eukaryotes in that they contain only a single loop of DNA stored in an area named the nucleoid. The DNA of the eukaryote is found on chromosomes. Prokaryotic DNA also lacks the proteins found in eukaryotic DNA. Prokaryotes have a larger surface area to volume ratio. This gives the Prokaryotes a higher metabolic rate, a higher growth rate and thus a smaller generation time as compared to the Eukaryotes.

Answer 3

the respond is D. Nucleic acids make up DNA and RNA, that are present in the two Prokaryotes and eukaryotes. Mitochondria isfound purely in eukaryotes. Golgi vesicles is present in the two professional and eukaryotes. Prokaryotes have not got nucleus. while eukaryotes do.

Answer 4

eukaryotes are alot more complex than prokaryotes. eukaryotes have nucleus membrane, prokaryotes dont. eukaryotes have linear chromosomes, prokaryotes have circular chromosome. hope this is helpful :)

Answer 5

I used to know that...hmm....don`t really remember but hey I gotta mention I got a 2 out of 10 at that biology testpaper cuz I remember having a fight with a really good friend a night before the test...I haven`t learned those lessons by now and hey...it`s been some time since then...lol...good luck finding out tho..

Answer 6

prokaryotes have no membrane bound organelles, no visable nucleus. eukaryotes have membrane bound organelles, a visable nucleus and are generally more complex

Answer 7

Ask Stephen King. He knows because he wrote about it.

Answer 8

i dropped microbiology because of questions like that, but good luck!lol!
