The endoplasmic reticulum (ER) is involved in protein and lipid synthesis, as well as detoxification of drugs and metabolism of carbohydrates. It also plays a key role in transporting and folding proteins within the cell.
There are two types of endoplasmic reticulum (ER : The rough ER and the smooth ER.
The surface of the rough ER is covered with structures called ribosomes that make proteins. This is why the rough ER is associated with protein synthesis (the process of making new proteins).
The smooth ER is also associated with protein glycosylation (or adding sugar groups to newly made proteins), as well as [ via Protein Trafficking ], the export of cellular materials. The SER is associated in making lipids.

Does a paramicium have an endoplasmic reticulum?
Yes, a paramecium does not have an endoplasmic reticulum. It lacks membrane-bound organelles, including the endoplasmic reticulum. This unicellular organism mainly relies on its cilia for movement and other structures for basic cellular functions.
What is the organelle that synthesizes lipids?
The endoplasmic reticulum is the organelle responsible for synthesizing lipids in a cell. It has two regions where lipid synthesis occurs: the smooth endoplasmic reticulum (SER) and the nuclear envelope. Lipids produced in the SER are important for various cellular functions, such as building cell membranes and storing energy.
Do plants have endoplasmic reticulum?
Yes, plants have endoplasmic reticulum (ER). It is a vital organelle in plant cells involved in various functions such as protein synthesis, lipid metabolism, and calcium storage. The ER in plants is structurally similar to that in animal cells.
Do all cells have Endoplasmic Reticulum?
No, not all cells have Endoplasmic Reticulum (ER). The presence and amount of ER can vary depending on the type and function of the cell. Cells that are actively involved in protein synthesis and secretion typically have a higher amount of ER compared to cells that do not have those functions.
Which of these organelles is coverd in ribosomes?
The rough endoplasmic reticulum is covered in ribosomes. In fact, it is called 'rough' because of the presence of ribosomes which give it a rough looking appearance. Technically, the rough endoplasmic reticulum is actually the region of the greater 'endoplasmic reticulum' where protein synthesis takes place. Another region of the endoplasmic reticulum is the 'smooth endoplasmic reticulum' where lipids are synthesized and other metabolic functions take place. The quantity of rough versus smooth endoplasmic reticulum is somewhat in flux and varies based on the needs of the cell.
What does the smooth endoplasm reticulum do for the cell?
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.
What are non examples for endoplasmic reticulum?
Mitochondria, Golgi apparatus, and lysosomes are non-examples of endoplasmic reticulum. These organelles serve different functions within the cell compared to the endoplasmic reticulum.
Does a paramicium have an endoplasmic reticulum?
Yes, a paramecium does not have an endoplasmic reticulum. It lacks membrane-bound organelles, including the endoplasmic reticulum. This unicellular organism mainly relies on its cilia for movement and other structures for basic cellular functions.
Where can one view images of a smooth endoplasmic reticulum?
To view images of smooth endoplasmic reticulum one could look for biology books. Smooth endoplasmic reticulum has functions with the production in several metabolic processes, it is "smooth" because it is not studded with ribosomes.
What organelle functions as a pathway to ship proteins and is dotted with ribosomes?
Endoplasmic Reticulum!
What builds proteins for cell functions?
Proteins are made in the Rough Endoplasmic Reticulum.
How are the functions of the endoplasmic reticulum and Golgi apparatus related?
In microbiology cells ( cytology).
How are the functions of the endoplasmic reticulum and Golgi and apparatus related?
In microbiology cells ( cytology).
What are the functions of the ribosomes and Golgi bodies.?
The Endoplasmic Reticulum and then is transfered to the Golgi bodies.

What organelle acts as the highway to transport proteins?
endoplasmic reticulum
