What organelle wouldn’t have a job if the smooth and rough ER didn’t work?
ruslelena [56]

Answer: The Golgi apparatus.

Explanation: I believe it is the Golgi apparatus as the Rough ER and Smooth ER create proteins and sort them in to piles before sending to the Golgi apparatus to deliver.

Remember: Proteins have many functions and are needed severely to perform those actions that without the Golgi apparatus, those proteins wouldn’t be able to be transported.
