how are the functions of the endoplasmic reticulum and the golgi apparatus related?
 The function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system, it works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA, structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus, the membranes are slightly different from cell to cell and a cell’s function determines the size and structure of the ER.
