Difference Between Smooth and Rough Endoplasmic Reticulum

The difference lies between the two is that the Smooth Endoplasmic Reticulum is not bounded by the ribosomes and is known for storing the lipids and proteins. Meanwhile, the Rough Endoplasmic Reticulum is bounded by the ribosomes and store proteins.
 
 
 
The another most essential component of the eukaryotic cell is the Endoplasmic Reticulum or ER. It occupies almost 10 percent of the total cell volume. ER is of two type smooth and rough. Though both share some common features too but differ in some. ER is membrane-bounded and is made up of cisternae, which is the network like structure.
 
ER works for the chemical compounds required by the cell for its inner and outer environment. ER produce, sorts and transports these chemical compounds along with the storing of some of them like proteins and lipids.
 
The ER has cavities in it, which occupies space in the cytosol, the lumen is the internal space present. The ER is connected to the nuclear membrane as well as from the cytosol by forming a connecting bridge between them.
 
These were the essential features of the ER, but as we know even they exist in two types, which are smooth and the rough and so with the help of this content we will distinguish both of them.

Meaning
Smooth ER appears like containing many circular marks which are the interlocking tubular sheets and they may be varied in look and function as well. Rough ER looks like the arrangement of the double membranes which are spotted with the ribosomes all over. They appear consisting of the parallel sheets of membrane.

Smooth ER is found near the cell membrane. Rough ER is found near the cytoplasm.
Originates from Rough endoplasmic reticulum by giving off the ribosomes. From nuclear membrane.

Dear student 
Both the smooth and rough endoplasmic reticulum help in the production and storage of proteins The main difference is that one contains ribosomes on it and the other does not.
The rough endoplasmic reticulum (RER) has ribosomes on its surface. This is what give the RER a "rough" appearance. Rough ER looks like sheets.The RER synthesizes (makes) and packages proteins. The RER is attached to the nuclear membrane. The Golgi apparatus tends to be on the other side of the RER.
The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids. Cells that produce oils have a higher ratio of SERs than do other cells. The smooth endoplasmic reticulum can be found dispersed throughout the cytoplasm of the cell.
Hope this helps 
Good Luck 
Cheers
