What does the rough ER have and what is its function?
A
The rough ER does not have ribosomes. The function of the rough ER is to process lipids and carbohydrates to be exported from the cell.
B
The rough ER has ribosomes. The function of the smooth ER is to process proteins to be exported to the cell, so the cell does have proteins.
C
The rough ER has ribosomes. The function of the rough ER is to process proteins to be exported from the cell.
D
The rough ER has ribosomes. The function of the rough ER if to process lipids and carbohydrates to be exported from the cell.
E
The rough ER does have ribosomes. The function of the smooth ER is to process proteins to be exported from the cell.
Explanation: 

Detailed explanation-1: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Detailed explanation-2: -The major function of the smooth endoplasmic reticulum is the detoxification of the body from drugs consumed and metabolic wastes produced. The major function of the rough endoplasmic reticulum is protein synthesis and their folding into proper quaternary structures.

Detailed explanation-3: -Presence of ribosomes on the endoplasmic reticulum makes it rough. The function of ribosomes is protein synthesis. Thus, the endoplasmic reticulum and the ribosomes function together to produce proteins and transport them to their final destination.
