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 type of cellular road in cells. Rough ER has ribosomes (another cell part) on it, while Smooth ER doesn't have ribosomes. Endoplasmic reticulum is a network of tubules, vesicles and sacs that are interconnected.They may serve specialized functions in the cell including protein synthesis, sequestration of calcium, production of steroids, storage and production of glycogen, and insertion of membrane proteins.he endoplasmic reticulum (ER) is an organelle that appears in all eukaryotic cells, usually surrounding the nucleus. The ER is made of a series of membranes that extend throu â¦ ghout the jelly-like cytoplasm and kind of form a maze.
