What does the golgi apparatus do for the cell?

Answer 1

The Golgi apparatus (also called the Golgi body, Golgi complex, or dictyosome) is an organelle found in typical eukaryotic cells. It was identified in 1898 by the Italian physician Camillo Golgi and was named after him. The primary function of the Golgi apparatus is to process and package macromolecules synthesised by the cell, primarily proteins and lipids. The Golgi apparatus forms a part of the endomembrane system present in eukaryotic cells.

Function
Cells synthesise a large number of different macromolecules required for life. The Golgi apparatus is integral in modifying, sorting, and packaging these substances for cell secretion (exocytosis) or for use within the cell. It primarily modifies proteins delivered from the rough endoplasmic reticulum, but is also involved in the transport of lipids around the cell, and the creation of lysosome. In this respect it can be thought of as similar to a post office; it packages and labels "items" and then sends them to different parts of the cell.

Enzymes within the cisternae are able to modify substances by the addition of carbohydrates (glycosylation) and phosphate (phosphorylation) to them. Proteins are also labelled with a signal sequence of molecules which determine their final destination. For example, the Golgi apparatus adds a mannose-6-phosphate label to proteins destined for lysosomes.

Vesicles which leave the rough endoplasmic reticulum are transported to the cis face of the Golgi apparatus, where they fuse with the Golgi membrane and empty their contents into the lumen. Once inside they are modified, sorted, and shipped towards their final destination. As such, the Golgi apparatus tends to be more prominent and numerous in cells synthesising and secreting many substances: plasma B cells, the antibody-secreting cells of the immune system, have prominent Golgi complexes.

Once the proteins reach the trans face, the trans-Golgi network (TGN), they are placed into coated transport vesicles and bud off to reach their final destinations. The form of the vesicle is determined by the type of protein and the label it acquired.

Answer 2

Golgi Apparatus, also Golgi body or Golgi complex, network of stacked sacs found within nucleated cells that store, package, and distribute the proteins and lipids made in the endoplasmic reticulum.

The Golgi apparatus was first described by Italian anatomist Camillo Golgi in the late 19th century. Located near the nucleus, each apparatus consists of a stack of six or seven flattened, membrane-bound sacs, or cisternae, each separated by a narrow space. The Golgi apparatus is cup-shaped with the convex end, or cis cisterna, facing the cell nucleus and the concave end, or trans cisterna, facing the cell surface. The number of Golgi apparatus in each cell varies but averages between 10 and 20 in animal cells and up to several hundred in plant cells.

Proteins and lipids manufactured in the endoplasmic reticulum bud off in tiny, hollow structures, or vesicles, and fuse with the cis cisterna of the Golgi apparatus. The proteins and lipids move progressively through the stack of cisternae until they reach the trans cisterna. There they may be modified by the attachment of lipids or carbohydrates. The proteins and lipids are enclosed in a membrane to form a vesicle so that they do not affect the rest of the cell. The vesicles are then sorted and their destination is determined.

Proteins that are meant to return to the endoplasmic reticulum carry a distinctive tag. The Golgi apparatus recognizes the tag and transports the proteins back to the endoplasmic reticulum. Some proteins and lipids are sent to the surface of the cell to be released into the external environment. Others are transferred to the small structures that hold digestive enzymes, called lysosomes.

The Golgi apparatus also manufactures long-chained sugars called polysaccharides that cells secrete into their external environments. Examples include cellulose and pectin used to construct plant cell walls, and the polysaccharides in the mucus of animal cells.

Answer 3

The Golgi apparatus protects the cell wall.

Answer 4

Golgi Apparatus Function
The Golgi apparatus is analogous to the finishing and packing room in a factory. Once the ribosome finishes manufacturing a protein in the rough ER, the protein needs to be prepared for use or export. Special enzymes will trim off any extra amino acids, and then the unfinished protein moves through channels in the smooth ER.
Eventually, some of the smooth ER membrane is pinched off as a SPHERICAL VESICLE. The proteins are either contained inside these structures or are carried on their surfaces. These vesicles are absorbed by the Golgi apparatus, and proteins are processed as they pass from one sac to the next. As the proteins move they are processed. When the protein is ready for export, it is pinched off of the Golgi and released into the cytoplasm.

Answer 5

So it doesn't appear any of the previous posters actually answered your question (but they are quite good at copying and pasting info from the web). Anyway, now that you know what a golgi appartus does and know more than what you need to know about the Golgi, you have probably already guessed that the answer to your question is NO, gogli apparati also are found in plant cells and you would expect this considering what the golgi does. Remember that plants make proteins/enzymes too, and these proteins need to be processed. They also secrete these proteins and enzymes. Nearly every eukaryote needs a golgi....

Answer 6

The golgi apparatus, or golgi complex, is like the cell's delivery system, and it also filters out harmful substances. p.s. remember to capitalize golgi!

Answer 7

golgi bodies do all the function written below
1 modification,packaging and synthesizing of cells
2 protect the cell wall
3 transport of materials to various parts of the cell
4 make/synthesize lysosomes

Easy Enough !

Answer 8

golgi bodies protect the cell wall

Answer 9

It packages molecules for transport in the cell
