If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why?

The endoplasmic reticulum helps make and transport proteins to the Golgi apparatus. The Golgi modifies, sorts, and packages proteins it receives from the ER, so without the ER, the Golgi would not function properly. Mitochondria produce energy, and ribosomes make proteins rather than receive them from the ER.
