The endoplasmic reticulum (ER) is a large network of membrane-bound tubes and sheets.
It looks like long tubules or round or oblong bags (vesicles).
There are two types of ER
I. Rough Endoplasmic Reticulum (RER)
RER looks rough under a microscope because it has particles called ribosomes attached to its surface.
The ribosomes are the sites of protein manufacture.
II. Smooth Endoplasmic Reticulum (SER).
SER helps in the manufacture of fat molecules, or lipids, important for cell function.
Some of these proteins and lipids help in building the cell membrane. This process is known as membrane biogenesis.
Some other proteins and lipids function as enzymes and hormones.
Functions of Endoplasmic Reticulum :
ER is to serve as channels for the transport of materials (especially proteins) between various regions of the cytoplasm or between the cytoplasm and the nucleus.
The ER also functions as a cytoplasmic framework providing a surface for some of the biochemical activities of the cell.
In the liver cells of the group of animals called vertebrates , SER plays a crucial role in detoxifying many poisons and drugs
I have given it in point form to make it easier.Hope this is a good contribution from a 13 year old.............
It fucntions in the synthesis of lipids, and proteins. It provides attachment for ribosomes. It is composed of membranous sacs
It is the "delivery network" that serves as the internal delivery system for the cell. It is also described as a tube-like network.

smooth endoplasmic reticulum
Well, rough endoplasmic reticulum (ER) contains ribosomes. Also, proteins synthesized on these ribosomes are collected in the ER for transport throughout the cell.Sources - My textbook and cellsalive.com
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)
They can be attached to Rough ER(Endoplasmic Reticulum)
Some Ribosomes are found stuck to the surface of the Endoplasmic Reticulum.
endoplasmic reticulum
Endoplasmic Reticulum, or Reticulum for short.
the endoplasmic reticulum is in both plant and animal cells. there is the smooth endoplasmic reticulum (SER) and then there is the rough endoplasmic reticulum (RER)
No because if they been connected then it be smooth endoplasmic reticulum or the rough endoplasmic reticulum and it will be one of the both :p
What are some diseases that affect the rough endoplasmic reticulum
the endoplasmic reticulum is transparent
The endoplasmic reticulum. Those with ribosomes are called "rough" without are called smooth.
Rough endoplasmatic reticulumRough endoplasmic reticulum
The surface for chemical activity in a cell is the endoplasmic reticulum. It is a membranous network found in the cytoplasm.
