Which cell structures cause the outer surface of the rough endoplasmic reticulum to appear rough?

The organelles that give the rough endoplasmic reticulum its rough appearance are ribosomes. When there are no ribosomes present it is called a smooth endoplasmic reticulum.

A maze of small canals that appears to connect the surface of a cell to its nucleus?
The endoplasmic reticulum is a series of interconnected membranes that form canals. This maze of small canals appear to connect the surface of a cell to its nucleus.
Describe the characteristics of the endoplasmic reticulum?
The endoplasmic reticulum is found in most cells. It's job is to transport proteins around the cell, ensuring it's survival. It's long, and curved in shape, and are in "stacks". It's made out of stacks of membranes. It is almost shaped like a 'wifi signal'. There are two kinds of endoplasmic reticulum: smooth and rough. The rough endoplasmic reticulum appears bumpy, as it will be carrying ribosomes. Smooth endoplasmic reticulum will not appear bumpy and will carry no ribosomes.
What structures are only found in animal cells?
There are many numerous organelles that appear in only animal cells--if I were to list tem all out it would be a huge list. A good reference website is Enchanted Learning. It has a lot of diagrams that you can look at, including both animal and plant cells.
Where do lipids appear primarily in a cell?
Lipids are created in the smooth endoplasmic reticulum of a cell. Many are used in the cell membrane, particularly phospholipids, whose double layer creates the basic structure of the membrane.
Why does rough ER look rough under the microscope?
ribosomes attached on the sides of the RER makes it look rough under the microscope .
What is structures are found on the surface of rough endoplamic reticulum but in smooth endopasmic reticulum?
The rough endoplasmic reticulum is characterized by ribosomes on the surface. When viewed (using an electron microscope) they appear as black dots. Ribosomes are responsible for translating mRNA into protein and use tRNA to obtain the amino acids needed for the process. Ribosomes are actually composed of two subunits (30S and 50S in humans).
Where does the endoplasmic reticulum appear?
It doesn't exactly "appear" but it is an organelle in eukaryotic cells and is found in the cytosol. I hope this helps. :)

What are the two functions of rough endoplasmic reticulum?
The reason rough endoplasmic reticulum is coz of ribosomes. The ribosomes cover the surface of rough endoplasmic reticulum and make it appear bumpy under microscopic magnification. Ribosomes are the sites where proteins are created from amino acids. Rough endoplasmic reticulum is connected with the outer envelope of the cell nucleus. The following are the main functions of rough endoplasmic reticulum: 1)The prime rough endoplasmic reticulum function is the production and processing of specific proteins at ribosomal sites that are later exported. 2)As I said before, rough endoplasmic reticulum function involves, creation of two types of proteins. One is the type which fortifies and gets embedded into the reticulum membrane. The other types are water soluble membranes which after creation at ribosomal sites, pass through the membrane and into the lumen. 3)The function of rough endoplasmic reticulum doesn't end there. The proteins that enter are further processed inside, the proteins are folded into the right three dimensional shapes and carbohydrates may be added. 4)The next rough endoplasmic reticulum function is to transport these ready proteins to the sites where the are required. They may also be sent to the Golgi bodies for further advanced processing, through vesicles.
Why does the rough ER appear pebbled?
There are ribosomes on the surface of the rough endoplasmic reticulum - these are ovular in shape and so make the surface appear 'rough'. Ribosomes are the site of protein synthesis - so this the rough ER is involved in the production of protein.
How many membranes does a smooth endoplasmic reticulum have?
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.

How many membranes does a endoplasmic reticulum have?
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.
What causes rough endoplasmic reticulun look rough under a miscrocope Rough er has ribosomes attached to it?
The rough endoplasmic reticulum(RER) appear rough when observed under a microscope because the outer region of the RER is studded with ribosomes which form sites for protein synthesis.
What makes the rough endoplasmic reticulum appear rough under the microscope?
the presence of ribosomes Many small ribosomes are attached to the surfaces of the rough ER. The rough ER processes proteins made by the ribosomes.
