It get created from the cell membrane, its' structure is similar to cell membrane.

the cell membrane gets inside to the cell and create ER. When the ER gets ribosomes on it, it becomes ROUGH ER or we called, R.E.R. The ER doesn't contains ribosomes on it, is SMOOTH ER or, S.E.R.

R.E.R. creates proteins and trans them to Golgi complexes. SER creates lipids and trans them to Golgi complexes.

* S.E.R. contains Ca++ ions inside it, and also amino acids and some vitamins.

Both ER structures are important to the organelles inside the cell. They can make limited moves inside the cell because of the ER complexes.
