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.esson Summary. Smooth endoplasmic reticulum is a cellular organelle made up of a tube-like structure that folds over on itself many times. An organelle is a sub-unit within a cell that has a specialized function. It is responsible for making products and undergoing processes that the cell needs to function.
The endoplasmic reticulum is a network of membrane-enclosed tubules and sacs, called cisternae. This network extends from the nuclear envelope throughout the cytoplasm (remember that the outer membrane of the nuclear envelope is continuous with the rough endoplasmic reticulum).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. See Figure 10.1.
