*pic attached* which structure in the cell shown in figure 7-3 below modifies sorts and packages proteins and other materials for storage or release from the cell?

Answer is A Golgi body.

The Golgi body or Golgi apparatus or dictyosome is a membrane bound sac like cell organelle found in most of the eukaryotic cells. The Golgi body plays very important role in processing the synthesized macromolecules such as protein and lipids in the cell. Actually this cell organelle modify, sort, and package proteins to be released outside the cell. For packaging and processing of protein, Golgi body works closely with rough endoplasmic reticulum.  

it takes hundreds of years to become stable.

if you have another question lmk.
