please exsplan what a vesicle and a golgi is?

Question

i have a power point due 2morrow i didnt start cause i have no clue what they are, my teacher wants us to teach ourselves every thing and that totaly sucks. so if you know all help is wanted!!!!

Answer 1

I hope you are taking biology and not geology or another subject because then the information I give you won’t help.

The two terms come together in the biology of a cell where a vesicle is a small tiny sack in a cell and a golgi is a cell organ found in eukaryotic cells. The golgi is on the cell membrane wall. Read the last article I cited and look at the numbered illustration (http://en.wikipedia.org/wiki/Image:Nucleus_ER_golgi.jpg) that should give you all that you need to do your Power Point Show.

According to Wikipedia: http://en.wikipedia.org/wiki/Golgi_organ
“The Golgi organ (also called Golgi tendon organ, neurotendinous organ or neurotendinous spindle), is a proprioceptive sensory receptor organ that is located at the insertion of skeletal muscle fibres into the tendons of skeletal muscle.

The Golgi organ should not be confused with the Golgi Apparatus, which is an organelle in the eukaryotic cell, or the Golgi stain, which is an histologic stain for neuron cell bodies.”

According to Wikipedia: http://en.wikipedia.org/wiki/Vesicle_%28biology%29
“In cell biology, a vesicle is a relatively small intracellular, membrane-enclosed sac that stores or transports substances. The vesicle is separated from the cytosol by at least one lipid bilayer. If there is only one lipid bilayer, they are called unilamellar vesicles; otherwise they are called multilamellar. Vesicles store, transport, or digest cellular products and waste. This biomembrane enclosing the vesicle is similar to that of the plasma membrane. Because it is separated from the cytosol, the intravesicular environment can be made to be different from the cytosolic environment. Vesicles can fuse with the plasma membrane, releasing their contents outside the cell. Vesicles are a basic tool of the cell for organizing metabolism, transport, enzyme storage, as well as being chemical reaction chambers. Many vesicles are made in the Golgi apparatus, but also in the endoplasmic reticulum, or are made from parts of the plasma membrane.”

According to Wikipedia: http://en.wikipedia.org/wiki/Golgi_apparatus
“The Golgi apparatus (also called the Golgi body, Golgi complex, or dictyosome) is an organelle found in most 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 the macromolecules such as proteins and lipids that are synthesized by the cell. It is particularly important in the processing of proteins for secretion. The Golgi apparatus forms a part of the endomembrane system of eukaryotic cells.”

Answer 2

The golgi apparatus packages proteins into tiny sacks called vesicles which move the proteins to the outside of the cell where it is needed.

Answer 3

Golgi app.- modifies/applications components with the intention to export them The vesicles- flow the changed components from the app. to the phospholipid membrane (cellular membrane), the place the components are then excreted. in addition they flow components in the process the golgi app. stable success!

Answer 4

Vesicle+ bladderlike structure, cyst, cavity or sac
Golgi -I think it is some king of apendage not sure?
