Answer:
Endoplasmic reticulum
Explanation:
The endoplasmic reticulum is a network of passageways found in the cytoplasms of eukaryotes for the purpose of manufacturing, processing, transporting, modifying, and folding proteins. There are two types of endoplasmic reticulum and they are the smooth and rough endoplasmic reticulums.
Unlike the smooth endoplasmic reticulum, the rough endoplasmic reticulum has ribosomes attached to it.
