The organelle is involved in the synthesis folding. The rough endoplasmic reticulum is a part of the endomembrane system that is present in the cytoplasm of the cell. Rough Endoplasm Reticulum Its Function In Life To To Package New Protein Up In Vesicles And Move Them To Where E Nuclear Membrane Biology Projects Cell Biology It belongs to a continuous membrane the nuclear. . Rough Endoplasmic Reticulum RER is a flat endoplasmic reticulum that had ribosomes attached to its outside surface. Functions of Rough Endoplasmic Reticulum RER It is the site for the synthesis of protein. One of the functions of rough endoplasmic reticulum include transportation of the ready proteins to the sites where they are required. They may also be sent to the Golgi bodies for further. 1-15 and 1-16. Functions of Endoplasmic Reticulum ER It is mainly responsible for the transportation of proteins and other carbohydrates to another organelle whic
