Definition of the Smooth ER. The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function.The main function of the smooth ER is to make cellular products like hormones and lipids.he interior of the smooth ER is called the lumen, which is enclosed by a phospholipid membrane, just like the membrane that encloses the entire cell. The number of smooth ER units in a cell depends on the type of cell and what its manufacturing needs are.
The rough endoplasmic reticulum (RER) which is continuous with the outer membrane of the nuclear envelope plays an important role in the sorting of proteins destined for various other locations in the cell, like the Golgi apparatus, the lysosomes and the plasma membrane.here are two types of endoplasmic reticulum (ER) - smooth and rough. The rough kind is covered with ribosomes on its outer surface and is involved in protein processing and sorting. The smooth ER is not associated with ribosomes and functions in lipid metabolism.
