Rough endoplasmic reticulum what is and function

Narration. 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 general function of the endoplasmic reticulum is to produce protiens for the cell to function. The rough ER in particular has many ribosomes on it's surface, while the smooth ER does not. These ribosomes give the rough ER it's distinct appearence under a microscope, and assist in making protiens.
