The rough endoplasmis reticulum (RER) is a stack of membranes inside most eukaryotic cells which have many ribosomes stuck to the surface for protein synthesis.
The rough endoplasmic reticulum in animal cells is involved in protein synthesis. It has ribosomes attached to its surface which help in the translation of mRNA into proteins. These proteins are then modified and transported to other parts of the cell.

It has only one. Just like all normal endoplasmic reticulums. And other organelles. In a cell there are membranous organelles with two layer membranes (nucleus and mitochondria), membranous organelles with one layer membrane (lysosome, peroxisome, endoplasmic reticulum and Golgi complex) and organelles not surrounded by membranes (ribosome, nucleolus, centrosome, centriole and basal bodies). Even though the endoplasmic reticulum is continuous with the nuclear envelope (that contains a two layer membrane) it only contains one membrane because only the outer layer of the nuclear envelope is continouous with the ER.
Any endoplasmic reticulum, smooth or rough, has one membrane. Just as there is one membrane around the nucleus, there is one around the ER. They appear to have many but they look this way because of how they are folded or formed. The Rough ER (RER) looks more like several pockets while the Smooth ER (SER) looks more like a bunch of tubes.
This really sounds like a homework question. To give you the answer to what obviously sounds like a homework question may be denying you the practice of researching the answer on your own. Education is not so much answering questions, it is also about practicing research methodologies that can be applicable to everyday situations. I am sorry, but this is a question that will not be handed to you so easily.
endoplasmic reticulum looks like a maze or a hallway. Endoplasmic reticulum's job is to carry protein. If you ever have a project and you have to represent what endoplasmic reticulum looks like, you could use bent pipe cleaners.
Endoplasmic reticulum can be either smooth or rough if it contains ribosomes.
Endoplasmic reticulum can be either smooth or rough if it contains ribosomes.
The portion of the endoplasmic reticulum that lacks attached ribosomes is called smooth endoplasmic reticulum (SER). It is involved in lipid metabolism, detoxification of drugs and toxins, and calcium storage and release in muscle cells.
It makes components of the cell membrane and are assembled and proteins are modified. Just like the Smooth Endoplasmic Reticulum.

A smooth endoplasmic reticulum can be used for transportation. I think there are more functions but I'm not sure what they are. Also, a rough endoplasmic reticulum is just like smooth endoplasmic reticulum except with ribosomes attached.

Hi,Smooth Endoplasmic reticulum Is just a piece of ER that does not have Ribosomes on it, and Rough ER is just Endoplasmic reticulum that have ribosomes on them.this is a picture of them both with differences.

They appear to have many but they look this way because of how they are folded or formed.
