Question

Answer 1

A simple way is to think of the Endoplasmic reticulum as the highway because it transports stuff throughout the cell. The rough endoplasmic reticulum contains ribosomes, which look like dots on a diagram and produces protein, while the smooth doesn't.

Answer 2

Transport system for the cell. Rough means there's ribosomes on the outside.
