Optometrists undergo extensive and intensive refractive and medical training mainly pertaining to the eye and the entrance criteria to attend optometry school is also highly competitive.
The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning. It processes and packages these macromolecules for use within the cell or for secretion.rimarily, the Golgi apparatus modifies proteins that it receives from the rough endoplasmic reticulum, however, it also transports lipids to vital parts of the cell and creates lysosomes. As part of eukaryotic cells, the Golgi apparatus works in unison with the endomembrane system.
Golgi Apparatus. A major organelle in most eukaryotic cells is the structure of membrane-bound sacs called the Golgi apparatus (or Golgi body, Golgi complex, dictyosome). It acts to process and package the macromolecules such as proteins and lipids that are synthesized by the cell.It has been likened to the cell's post office. major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
