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.
Rough ER is mainly found near the nucleus and the Golgi apparatus, whereas smooth ones extend to the periphery of the cell. The rough endoplasmic reticulum is studded with ribosomes, which give the granular appearance.The smooth ER has very few or no ribosomes.roportion: The proportion of smooth endoplasmic reticulum is very small, when compared to that of rough ER. Smooth ER is mostly found in cells that are actively involved in synthesis and metabolism of lipids. It is prominently seen in the liver, ovaries, testes, muscles, etc.
