I believe you are referring to the Rough ER, or the rough endoplasmic reticulum. It has many ribosomes on it which look like little black dots under a microscope and therefore it appears rough.
Yes, the rough endoplasmic reticulum is a membrane-bound organelle within a cell.
The organelle Rough Endoplasmic Protein synthesizes proteins.
The Rough Endoplasmic Reticulum (Rough ER).

The endoplasmic reticulum (specifically the rough endoplasmic reticulum) is the cell organelle that is packed with ribosomes. Ribosomes on the rough endoplasmic reticulum are involved in protein synthesis.
