what is the difference between eukaryotes and prokaryotes?
543214
Eukaryotes have organelles and are comparmentalized.  Prokaryotes do not have organelles and are not compartmentalized.

For eukaryotes, in the neucleus. For prokaryotes, the cytoplasm because they don't have a nucleus.

Eukaryotic means an organism has a nucleus...prokaryotic means it doesn't have a nucleus.

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.

Eukaryotic cell division is called mitosis while prokaryotic is known as binary fission (cell divides in half - forming two daughter cells which are genetically identical)\nE- Sex cells in diploid(two copies of chromosome) therefore organisms are produced through meiosis \nP- Organisms are haploid (one single copy of chromosome), No meiosis needed

Bacteria are prokaryotic organisms. They are mostly unicellular, and they have no nucleus and other cell structures.\n\nProtists and Fungi, on the other hand, are eukaryotes, which are unicellular or multicellular organisms that have a nucleus and complex structures like mitochondria and chloroplasts.\n\nfor more details, go to an encyclopedia website like http://www.wikipedia.org

B) Membrane-bound organelles\nThe procariotic cells are like a water-filled baloon, they are just a cover with water and other things (of course, this is only an example), while eukaryotic cells have compartiments.\nEvery cell has DNA, that's the way information is passed from cell to cell when they reproduce.\nRibosomes are important for producing proteins, every cell has to have them, even if with time they lose them.\nCytoplasm is the 75% of every cell, it's basically water, proteins and other things.

The prokaryote cell does not contain a nucleus. Prokaryote cells are only one celled organisms.\nEukaryote cells can be of one celled organisms, or multi-celled (like you and me). Eukaryote cells contain mitocondria, I don't beleave prokaryotes do.

That happened way back when eukaryotes split from prokaryotes. Eukaryotes have a nucleus.  Then eukaryotes split into animals, plants, fungus, etc... but they were still very tiny organisms at first.\n\nOpisthokonts separated from Archaeplastida\nThis was around 1.6-2.1 billion years ago.  "Modern" groups came about 80 million years ago.\n\nhttp://en.wikipedia.org/wiki/Eukaryotes#Origin_and_evolution

Prokaryotic cells do not undergo mitosis. Prokaryotic cells divide by fission,

Bacteria and Archea are similar in their energy conversion and metabolism where as archea and eukarya are similar in their ways of transcription, translation and DNA replication. Archea and Bacteria are also similar in that they are both prokaryotic.

Protozoa are microscopic organisms, bigger than Bacteria, they have evolved and they get food from eating Bacteria.\nWhen they get big enough they split into two exact copies and thereby reproduce and grow.

eukaryotes all have telomeres\n\nmost prokaryotes have circular DNA's --> therefore do not suffer from the same shortening DNA problems as in eukaryotic linear DNA's --> therefore no need for having telomeres.

The origin of the eukaryotic cell was a milestone in the evolution of life, since they include all complex cells and multi-cellular organisms. The timing of this series of events is hard to determine; Knoll (1992) suggests they developed approximately 1.6 - 2.1 billion years ago. Fossils that are clearly related to modern groups start appearing around 800 million years ago.\n\nrRNA trees constructed during the 1980s and 1990s left most eukaryotes in an unresolved "crown" group (not technically a true crown), which was usually divided by the form of the mitochondrial cristae. The few groups that lack mitochondria branched separately and so the absence was believed to be primitive, but this is now considered an artifact of long branch attraction and they are known to have lost them secondarily.\n\nTrees based on actin and other genes have painted a different and more complete picture. Most eukaryotes are now included in several supergroups:\n\nOpisthokonts Animals, fungi, choanoflagellates, etc. \nAmoebozoa Most lobose amoebae and slime moulds \nRhizaria Various amoeboid protozoa \nExcavates Various flagellate protozoa \nArchaeplastida Land plants, green and red algae \nHeterokonts Brown algae, diatoms, water molds, etc. \nAlveolates Ciliates, Apicomplexa, dinoflagellates, etc. \n\nThe heterokonts and alveolates may be part of a larger group that is ancestrally photosynthetic, called the chromalveolates, but this remains contentious. Otherwise the relationships between the different supergroups are mostly uncertain, and in particular there is dispute about where the root of the evolutionary tree belongs, and as a result what the earliest eukaryotes were like. A few small protist groups have not been related to any of the major supergroups, notably the centrohelids, apusozoans, and ebriids.\n\nEukaryotes are closely related to archaea, at least in terms of nuclear DNA and genetic machinery. In other respects, such as membrane composition, they are similar to eubacteria. Three main explanations for this have been proposed:\n\nEukaryotes resulted from the complete fusion of two or more cells, the cytoplasm forming from a eubacterium and the nucleus from an archaeon (alternatively a virus). \nEukaryotes developed from Archaea, and acquired their eubacterial characteristics from the proto-mitochondrion. \nEukaryotes and Archaea developed separately from a modified eubacterium. \nThe origin of the endomembrane system and mitochondria are also disputed. The phagotrophic hypothesis states the membranes originated with the development of endocytosis and later specialized; mitochondria were acquired by ingestion, like plastids. The syntrophic hypothesis states that the proto-eukaryote relied on the proto-mitochondrion for food, and so ultimately grew to surround it; the membranes originate later, in part thanks to mitochondrial genes (the hydrogen hypothesis is one particular version).
