Protein along with lipids form a lipoproteinous wall that surrounds the cell which is called plasma-membrane.for details got to below given link:\nhttp://en.wikipedia.org/wiki/Plasma_membrane

chloroplasts, flagella, contractile vacuoles and the eye spot for starters.

since each amino acid has a specific t-RNA for it, eukaryotes must have about 64 of them or so. must be equal to the number of codon possible= 4^3=64 (4 for A,U,C,G and 3 for the number of them in each codon).

Microtubules are protein structures found within cells, one of the components of the cytoskeleton. They have diameter of ~ 24 nm and length varying from several micrometers to possibly millimeters in axons of nerve cells. Microtubules serve as structural components within cells and are involved in many cellular processes including mitosis, cytokinesis, and vesicular transport.

Theory? I mean, I can think of the endosymbiotic theory, but that's eukaryotes. Perhaps you mean the organelle that carries out photosynthesis in prokaryotes?

None-- But the endoplasmic reticulum does come in contact at various times during the life cycle

1.Mitochondria have a set of double membranes, as do most bacteria; and the lipid composition of mitochondrial membranes shows no similarities with the eukaryotic cell cytoplasm. If mitochondria evolved inside of proto eukaryote, their membrane composition would be expected to be of the same material. Instead, it appears that mitochondrial membranes more closely resemble bacterial membranes in terms of lipid composition \n\n2.The inner-membrane infoldings in the mitochondria lend more credence to the symbiosis theory. the infoldings (cristae) "are adaptations that increase the surface area of oxidative enzymes, evolutionary analogues to the mesosomal membranes of many prokaryotes" . In addition, the cristae keep the various enzymes segregated according to use, as do bacteria\n\n3.Mitochondrial ribosomal RNA sequences bear much more in common with bacteria than with ribosomes in the eukaryotic cytoplasm. For example, n-formylmethionyl transfer RNA has been found to exist only in mitochondria and bacteria \n\n4. Not only do mitochondria possess their own DNA, but it is circular, as is bacterial DNA; and DNA synthesis is continuous as opposed to that of eukaryotic nuclear DNA. Furthermore, the ratio of guanine-cytosine base pairs in mitochondrial DNA is proportionately higher, as with bacteria, than in eukaryotic nuclear DNA\n\n5.Mitochondrial division resembles bacterial reproduction.  "Genetic recombination in (mitochondria) is far more reminiscent of phage and bacterial sexuality than it is of eukaryotic nuclear sexual behavior

A plasma membrane or cell membrane or plasmalemma structured bilayer of phospholipid and protein molecules.\nThe basic composition and structure of the plasma membrane is the same as that of the membranes that surround organelles and other subcellular compartments. The foundation is a phospholipid bilayer, and the membrane as a whole is often described as a fluid mosaic – a two-dimensional fluid of freely diffusing lipids, dotted or embedded with proteins, which may function as channels or transporters across the membrane, or as receptors. \n\n"The model was first proposed by S.J. Singer (1971) as a lipid protein model and extended to include the fluid character in a publication with G.L. Nicolson in "Science" (1972)."

Yes, it is C, pardner.\n\nHelps cell to continually turn over intracellular proteins before they get too old or nonfunctional. Breaks them up into lttle pieces. On the macro level, keeps you looking like yourself instead of slowly fading away.\n\n"Lysosomes contain various hydrolytic enzymes that are capable of digesting nucleic acids, polysaccharides, fats and proteins. The inside of a lysosome is acidic."\nhttp://biology.about.com/library/weekly/...\n\n2004 Nobel Prize:\n"Proteasomes are complex structures inside cells that break down proteins. Ubiquitin proteasome system is a barrel-shaped multi-protein complex that can specifically digest other proteins into short polypeptides and amiino acids in an ATP-driven reaction."\nhttp://en.wikipedia.org/wiki/proteasome...\n\n\nHere is a good site for checking out things in this subject area. It is a wonderful biology site.\n\nhttp://users.rcn.com/jkimball.ma.ultrane...\n\nThe Golgi apparatus functions in transporting materials out of the cell. \n\nDon't forget to pull up the urls and read more.

Living cells such as eukaryotes have many organelles such as: a nucleus, Mitochondria, Rough and smooth endoplasmic reticulum (rough has ribosomes on the surface of it), Golgi body, Lysosomes, cytoplasm, ribosomes and so on\nOther types of cells include prokaryotes, these don't have a nucleus or any other membrane bound organelles... they also have other organelles of which I can't really be bothered listing at the moment. hehe
