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 tubules and flattened sacs that serve a variety of functions in the cell. There are two regions of the ER that differ in both structure and function. One region is called rough ER because it has ribosomes attached to the cytoplasmic side of the membrane.The other region is called smooth ER because it lacks attached ribosomes. Typically, the smooth ER is a tubule network and the rough ER is a series of flattened sacs.The space inside of the ER is called the lumen.ne region is called rough ER because it has ribosomes attached to the cytoplasmic side of the membrane.
