Detailed explanation-1: -On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane. It does not have ribosomes on its membrane.
Detailed explanation-2: -The rough ER, which is covered by ribosomes on its outer surface, functions in protein processing. The smooth ER is not associated with ribosomes and is involved in lipid, rather than protein, metabolism.
Detailed explanation-3: -In contrast, the smooth endoplasmic reticulum has no ribosomes on its surface; thus, it appears smooth.
Detailed explanation-4: -Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell.
Detailed explanation-5: -The rough endoplasmic reticulum contains ribosomes and makes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell.
