Smooth ER lacks ribosomes, which are protein-producing organelles. Instead, they detoxify harmful substances and turn them into harmless substances, and they are involved in the production of hormones and lipids.
The SER lacks ribosomes embeded within the membrane of the ER. The "rough" description is given due to the visible ribosomal bodies covering the exterior surface.

The endoplasmic reticulum (ER) is an intricate network within cells that has unique functions. It is involved in protein synthesis, lipid metabolism, and calcium storage. The ER also plays a crucial role in protein folding and quality control.
Ribosomes:D
Smooth ER is found in cells that are involved in lipid metabolism, such as liver and muscle cells. Rough ER is found in cells that are responsible for protein synthesis, such as cells in the pancreas and salivary glands.
Organelles involved in protein synthesis include the ribosomes, which are the sites where protein synthesis occurs, and the endoplasmic reticulum (ER), where proteins are further processed and modified. Additionally, the Golgi apparatus packages the synthesized proteins into vesicles for transport within and outside the cell.
Ribosomes are the organelles that can be either bound to the endoplasmic reticulum (forming rough ER) or free in the cytoplasm. They are responsible for protein synthesis by translating mRNA into polypeptide chains.
The rough ER is the portion of the endoplasmic reticulum that has ribosomes attached to its surface. These ribosomes are involved in protein synthesis, producing proteins that are then transported and processed within the rough ER.
Rough endoplasmic reticulum (ER) has ribosomes on its surface, involved in protein synthesis, while smooth ER lacks ribosomes and is involved in lipid synthesis, detoxification, and calcium storage. Both types of ER are interconnected and help in cellular functions like protein and lipid metabolism.
Pancreatic cells contain a high concentration of organelles called mitochondria, which are responsible for producing energy in the form of ATP through cellular respiration. They also contain endoplasmic reticulum for protein synthesis and Golgi apparatus for packaging and processing proteins before secretion.
