Morphologically, there are ribosomes attached on the rough surface, but there are no ribosomes on the smooth surface.

1. Different appearance: rough endoplasmic reticulum: ribosomal particles are attached to the membrane. Slippery endoplasmic reticulum: smooth on the membrane, no ribosomes attached.
2. Different functions: The function of the rough endoplasmic reticulum is to synthesize proteins and transport them from the cell or transport them to other parts within the cell. Associated with the transport of secreted proteins, preliminary processing of proteins (coiling, folding, glycosylation).
Where protein synthesis is vigorous, the rough endoplasmic reticulum is developed. In nerve cells, the development of the rough endoplasmic reticulum is associated with memory. The function of the slippery endoplasmic reticulum is related to the synthesis, detoxification, and assimilation of sugars and lipids, and it also has the function of transporting proteins.

The main difference is that the rough endoplasmic reticulum is mostly flat sac-shaped, neatly arranged, and a large number of ribosomes are distributed on the surface of the membrane. It is a place for the synthesis, processing and sorting of secretory proteins, lysosomal proteins and membrane proteins.
There are no ribosomes on the membrane surface of the slippery endoplasmic reticulum. It is an important site for lipid synthesis and a detoxification site for certain hydrophobic compounds.
Rough endoplasmic reticulum action:
The function of the rough endoplasmic reticulum is to synthesize protein macromolecules and transport them from the cell or transport them to other parts of the cell. In cells where protein synthesis is vigorous, the rough endoplasmic reticulum is developed. In nerve cells, the development of the rough endoplasmic reticulum is associated with memory.
Smooth endoplasmic reticulum effect:
The function of smooth endoplasmic reticulum: it is related to the synthesis and assimilation of sugars and lipids, and also has the function of transporting proteins.
The endoplasmic reticulum is a fine membrane system within the cell. It is a system of pipes that intertwine membranes distributed in the cytoplasm. Between the two membranes is a flat cavity, sac, or cisterna.
Endoplasmic reticulum is divided into two categories, one is the rough endoplasmic reticulum with ribosomal particles attached to the membrane, and the other is the smooth endoplasmic reticulum with no ribosomes attached to it.
Endoplasmic reticulum is found in various eukaryotic cells except mammalian mature red blood cells. The endoplasmic reticulum is an interconnected lamellar or tubular system composed of biological membranes, and the interstitial space between the membranes is called a cisterna, which is usually not directly connected to the extracellular space and the cytoplasmic matrix.
On the one hand, this intracellular membrane system constitutes a pathway for the transport of intracellular substances, and on the other hand, it provides a broad reaction area for various enzyme reactions in the cell. The endoplasmic reticulum is continuous with the Golgi apparatus and the nuclear envelope.
