Does anyone know how a Golgi Apparatus looks like?

maybe u can check these websites, or just simply search in google images:\n\nhttp://employees.csbsju.edu/hjakubowski/classes/ch331/cho/ergolgi.jpeg\n\nhttp://www.eccentrix.com/members/chempics/Slike/cell/Golgi_apparatus.jpg\n\nhttp://micro.magnet.fsu.edu/cells/golgi/golgiapparatus.html \n\nhope this will help :)

All proteins start being manufactured by ribosomes in the cytoplasm of the cell. Sodium-potassium pump proteins will probably need to be slightly chemically modified before they are inserted into the plasma membrane, so they will contain a 15-30 amino acid long sequence at their N-terminus (in the middle of which will be a region of around 10 hydrophobic amino acids) which will target them for the endoplasmic reticulum. \n\nOnce these first signal sequence amino acids have been joined together by the ribosome, a protein called a signal recognition particle (SRP) binds to the recognition sequence on the half-synthesised protein. The SRP often halts protein synthesis. Once this has happened, the SRP-protein-ribosome complex docks onto an SRP-receptor (which also contains a ribosome receptor). The SRP then detaches from the protein, and so protein synthesis can resume. The ribosome receptor now acts as a translocation tunnel, allowing the extending protein to transverse the ER membrane. In the case of the sodium-potassium pump protein, the finished protein will emerge into the ER lumen and the pore of the tunnel will close. \n\nThe protein will leave the ER in a transport vesicle which bud off from the specialised ribosome-free regions of the ER situated adjacent to the Golga apparatus. From here they are delivered to the cis face of the Golgi and pass through the Golgi cisternae by repeated cycles of vesicle budding and fusion. \n\nFinally the protein will bud off from the trans cisternae in the golgi body and get directed to the plasma membrane, where it will get recognised and threaded through, forming a channel.\n\nIn summary: The protein is made by a ribosome, translocated to the ER, buds off in a vesicle to the golgi, and moved to the membrane.

Google images tab is the best way. \nyou might want to look here too\nhttp://en.wikipedia.org/wiki/Antenna_(biology)

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

golgi bodies are organelles found in eukaryotic plant and animal cells. They process and package molecules synthesized by the cell, which are usually lipids or proteins.

Its appearance under a microscope.\n\nPersonally, I think Giardia lamblia looks a little like a balloon with eyes and a modest length of string tied on it...

The Golgi apparatus is a membrane-bound structure with a single membrane. It is actually a stack of membrane-bound vesicles that are important in packaging macromolecules for transport elsewhere in the cell. The stack of larger vesicles is surrounded by numerous smaller vesicles containing those packaged macromolecules. The enzymatic or hormonal contents of lysosomes, peroxisomes and secretory vesicles are packaged in membrane-bound vesicles at the periphery of the Golgi apparatus.

it's located in the cytoplasm

hey! read a fish book. they always how a diagram of disecting parts or body anatomys. hint: for more info... go to this website:

The Golgi body is responsible for synthesis and packaging of chemicals in the cell. These chemicals are then packaged into thin membranes and used either by the cell or outside of it. \n\nSo, without a Golgi, the cell would not be able to produce the chemicals essential for its life. Hence, the cell would 'die'. \nHowever, if the cell is producing chemicals for external use, the lack of a Golgi body would not 'kill' it, but would only prevent it from fulfilling its function eg - secreting saliva.
