Prokaryotes\n1. Their DNA is not enclosed within a membrane.\n2. Their DNA is not associates with histones (the proteins that DNA wrap themselves around in eukaryotic cells)\n3. They lack organelles.\n4. Their cell walls almost always contain peptidoglycan.\n5. They divide through binary fission.\n\nAtomicQuasar, all bacteria are prokaryotes, and thanks for adding that the prokaryotes are smaller and simpler and have plasmid.\n\nEukaryotes\n1. Their DNA is found in the cell's nucleus.\n2. DNA can be found on multiple chromosomes.\n3. They have a number of membrane-enclosed organelles.  Including mitochrondia, endoplasmic reticulum, and Golgi complex.\n4. Their cell walls are simple in chemical make-up.\n5. They usually divide through mitosis.

Archaea, Eukaryota and Bacteria are the fundamental classifications in what is called the three-domain system. Like bacteria, Archaea are single-celled organisms lacking nuclei and are therefore prokaryotes, classified as Monera in the alternative six-kingdom taxonomy. They were originally described in extreme environments, but have since been found in all types of habitats.\n\nThe archaeal lipids are unique because the stereochemistry of the glycerol is the reverse of that found in bacteria and eukaryotes. This is strong evidence for a different biosynthetic pathway. \nMost bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids, whereas archaea have membranes composed of glycerol-ether lipids. Even when bacteria have ether-linked lipids, the stereochemistry of the glycerol is the bacterial form. These differences may be an adaptation on the part of Archaea to hyperthermophily. However, it is worth noting that even mesophilic archaea have ether-linked lipids. \nArchaeal lipids are based upon the isoprenoid sidechain. This is a five-carbon unit that is also common in rubber and as a component of some vitamins common in bacteria and eukaryotes. However, only the archaea incorporate these compounds into their cellular lipids, frequently as C-20 (four monomers) or C-40 (eight monomers) side-chains. In some archaea, the C-40 isoprenoid side-chain is actually long enough to span the membrane, forming a monolayer for a cell membrane with glycerol phosphate moieties on both ends.

>>>>>(IT IS NOT HOMEWORK! i am competing with a friend for the >>>>> best example)\n\nAnd cheating by asking strangers on the internet. I like the way you think.\n\nThe most extreme example of bacterial endosymbiosis amongst mammals is without a doubt the presence of mitochondria. You might not relaise it but mitochondria are stable line bacterial endosymbionts, complete with there own genetic structure. It's hard to top that.\n\nAfter that probably comes the entire rumen structure of ruminants. Its incredibly cmmplicated, but basically the stomach of cows and sheep is one massive bacterial fermentor. The cow eats grass but is totally unable to digest it. Instead it grinds the grass up fine and swallow sit to wet it. It leave sit in the stomach to fermenta while then brings it up to shew again after the bacteria have softened it. The food then goes back down for even more fermentation in the other three chambers of the stomach. To add to the elegance of this system cows don't just excrete their urea through their kidneys like other mammals. Urea is  a waste in mammals and is poisonous, but it is also a good fertiliser. Ruminants excrete their urea through their salivary glands. It then passes into the stomach and what was a poison to the cow becomes fertiliser for the bacetria, who convert the waste urea into protein that the cow can use. As a reuslt ruminants are the only mammals in the world tht can survive with no protein input intheir deit at all. Which explains why they have been so extraordinarily successful at surviving in harsh and low nutrient environments.\n\nLast comes the biosynthesis of vitamins. Mammals can't   make their own vitamins, they normally need to take it in on the food. However numerous mammals species from dogs to horses are able to harvest those vitamins from bacteria that grow in their guts. So although a dog lives on a diet that is horrendously deficient in 3 or four vitamins it never gets ill or needs to take vitamin tablets. Which is pretty clever.

Most prokaryotes are bacteria, and the two terms are often treated as synonyms. Unicellular is another term for them.

diverse group of bacteria (prokaryotes), sometimes called the archaea and considered a major group unto themselves. Archaebacteria are contrasted with the Eubacteria, from which they differ biochemically in the arrangement of the bases in their ribosomal RNA and in the composition of their plasma membranes and cell walls. There are three major known groups of Archaebacteria: methanogens, halophiles, and thermophiles. The methanogens are anaerobic bacteria that produce methane. They are found in sewage treatment plants, bogs, and the intestinal tracts of ruminants. Ancient methanogens are the source of natural gas. Halophiles are bacteria that thrive in high salt concentrations such as those found in salt lakes or pools of sea water. Thermophiles are the heat-loving bacteria found near hydrothermal vents and hot springs. Many thermophiles are chemosynthetic (see chemosynthesis), using dissolved sulfur or other elements as their energy source and iron as a means of respiration. Archaebacteria emerged at least 3.5 billion years ago and live in environments that resemble conditions existing when the earth was young.

The very oldest species on Earth are the cyanobacteria, which seem to have been around virtually unchanged for nearly 4 billion years. This is based on fossils of that age that have been compared under high-powered microscopes to existing species of these bacteria. Other bacteria that are about as old are the archaea, which thrive in acidic, high- temperature, or high-radiation environments. \n\nAnother remnant of ancient organisms includes the stromatolites, mounds of algae and bacteria that today grow in the Bahamas, Shark's Bay Australia, and a few other limited environments. They have been around, also largely unchanged, for over 3 billion years and at one time were the Earth's dominant form of life. \n\nOn the animal side of things, the brachiopod Lingulaa is probably the oldest, having existed nearly unchanged for over 500 million years, and the horseshoe crab (limulus) has been on the planet for several hundred million years, too. Since the average "lifespan" of a species is only a few million years, having such ancient species around is very impressive. \n\nA good book about the earliest life is "Cradle of Life" by J. William Schopf. He is one of the premier scientists doing this sort of research. At a more advanced level, he has edited two scientific books, "Earth's Earliest Biosphere" and "The Proterozoic Biosphere", which should be in your university's geology or science library.

Artemia Salina are Xerophiles.\n\nOrganisms that thrive in what, for most terrestrial life-forms, are intolerably hostile environments.1 The majority of known extremophiles are varieties of archaea and bacteria. They are classified, according to the conditions in which they exist, as thermophiles, hyperthermophiles, psychrophiles, halophiles, acidophiles, alkaliphiles, barophiles, and endoliths. These categories are not mutually exclusive, so that, for example, some endoliths are also thermophiles. \n\nThe discovery of extremophiles points out the extraordinary adaptability of primitive life-forms and further raises the prospect of finding at least microbial life elsewhere in the Solar System and beyond.2 There is also growing support for the idea that extremophiles were among the earliest living things on Earth.\n\nHere is a good link:\nhttp://www.daviddarling.info/encyclopedia/E/extremophile.html
