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.

∙ 13y agoThere are two kinds of Endoplasmic Reticulum:
Rough Endoplasmic Reticulum (Rough ER): The surface of rough endoplasmic reticulum is covered with spherical organelles called ribosomes. Rough endoplasmic reticulum is involved with protein synthesis.
Smooth Endoplasmic Reticulum (Smooth ER): This type of endoplasmic reticulum is involved with lipid synthesis and detoxification of toxic matters.

∙ 10y agoAny 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.

What is the function of Rough endoplasmic reticulum in animal cell?
Endoplasmic reticulum is like a transport and manufacturing pipeline, for many biochemical compounds. Endoplasmic reticulum function is dependent on its type. There are three types of endoplasmic reticulum, which are:Rough Endoplasmic Reticulum (RER)Smooth Endoplasmic Reticulum (SER)Sarcoplasmic Reticulum (SR)
How many membranes does a endoplasmic reticulum have?

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.
What form parts of cell membranes and many of the cell's organelles?
The answer is proteins.
What is the image and parts of plant cell?
There are many parts to a plant cell. The cell contains amyloplasts, ATP, cell membranes, cell walls, centrosomes, chlorophyll, chloroplast, christae, cytoplasm, golgi complex, granum, mitochondrion, nuclear membranes, nucleolus, nucleus, ribosomes, enough and smooth endoplasmic reticulum, stroma, and vacuoles.
Endoplasmic reticulum where proteins are built?
Rough endoplasmic reticulumn holds many ribosomes.It provides the surfce area for protein sythesis.
What are the hallways of the cell?
ENDOPLASMIC RETICULUM (ER) Endoplasmic Reticulum The endoplasmic reticulum is a network of membranes found within almost all eukaryotic cells. The membranes are connected to the membrane of the cell’s nucleus and are important for many cellular processes such as protein production and the metabolism of lipids and carbohydrates. The endoplasmic reticulum includes both the smooth ER and the rough ER. The smooth ER is a smooth membrane and has no ribosomes, whereas the rough ER has ribosomes that are used to produce proteins.
Which is an organelle found in the cytoplasm has a smooth outer membrane and greatly folded inner membrane?
Endoplasmic Reticulum: a series of highly folded membranes, "rough" endoplasmic reticulum has many ribosomes attached to it. "Smooth" endoplasmic reticulum has no ribosomes attached to it and is the structure where fats (lipids) are made but both types of endoplasmic reticulum carry materials through the cytoplasm.
How many are endoplasmic reticulum?
There are ribosomes in the rough endoplasmic reticulum, but they are not called cells. The rough endoplasmic reticulum and the ribosomes are all in a cell and ribosomes are organelles in the rough endoplasmic reticulum.
Is it true that Many membrane proteins are made by the smooth endoplasmic reticulum?
No, it is the rough endoplasmic reticulum.

Many membrane proteins are made by the Smooth endoplasmic reticulum true or false?
true

What is the of the endoplasmic reticulum?
here are several definitions i found on dictionary.comDictionary.com Unabridged (v 1.1) - Cite This Source - Share Thisendoplasmic reticulum-noun Cell Biology. a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum), involved in the transport of materials.American Heritage Dictionary - Cite This Source - Share This endoplasmic reticulumn. A membrane network within the cytoplasm of cells involved in the synthesis, modification, and transport of cellular materials.endoplasmic reticulum (ěn'də-plāz'mĭk) Pronunciation KeyAn organelle consisting of a network of membranes within the cytoplasm of eukaryotic cells that is important in protein synthesis and folding and is involved in the transport of cellular materials. The endoplasmic reticulum can be continuous in places with the membrane of the cell nucleus. The function of the endoplasmic reticulum can vary greatly with cell type, and even within the same cell it can have different functions depending on whether it is rough or smooth. ◇ The rough endoplasmic reticulum is a series of connected flattened sacs that have many ribosomes on their outer surface. Rough endoplasmic reticulum synthesizes and secretes serum proteins (such as albumin) in the liver, and hormones (such as insulin) and other substances (such as milk) in the glands. ◇ The smooth endoplasmic reticulum is tubular in form and is involved in the synthesis of phospholipids, the main lipids in cell membranes. Smooth endoplasmic reticulum is the site of the breakdown of toxins and carcinogens in the liver, the conversion of cholesterol into steroids in the gonads and adrenal glands, and the release of calcium ions in the muscles, causing muscle contraction. The smooth endoplasmic reticulum also transports the products of the rough endoplasmic reticulum to other cell parts, notably the Golgi apparatus. See more at cell.my knowlage: an organelle found inside of some cells often abbreaviated as ER. A rough ER is an ER with ribosomes stuck to it, and a smooth ER is one without ribosomes. the ER is often found around the nucleus. it can sometimes be confused with the Golgi complex because of their similar looking shape.this is alot of info!!!!!hope it helps!!!!!!
What form parts of cell membranes and many of the cell's organelles?
The answer is proteins.
What is an animal cell's structures?
Animal cells have many different structures. However, the major ones are: Nucleus Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Golgi Apparatus Mitochondria Ribosomes Lysosomes Cytoskeleton Vacuoles
What organelle is attached to the nuclear envelope?
I don't think there is cell organelle surrounding the nuclear membrane because the nuclear membrane has many openings for nuclear traffic so i don't think there is any thing around it.but if you think i am wrong i am sorry:)
