Document Summary
The cell is so small and simple in appearance when viewed with the light microscope that is dif cult to conceive that each cell is a living entity. Equally amazing is the fact that the functioning of our organs and systems relies upon the complex functions of the cells. Golgi apparatus: responsible for packaging proteins from the rough endoplasmic reticulum into membrane-bound vesicles. Two types of vesicles are produced by the. Golgi bodies: secretory vesicles, transport proteins to the cell membrane for release into the extracellular environment, and storage vesicles, such as lysosome, whose contents are stored within the cell. Secretory vesicle: produced by golgi apparatus and used to transport various types of proteins out of the cell for use in other parts of the body. The process which the cell rallies proteins through the membrane into the extracellular environment is called secretion.
