\nRER stands for Rough Endoplasmic Reticulum, which is characterized by having ribosomes attached to its surface.
\n<\/section>\n
\nThe endoplasmic reticulum (ER) is a network of membranes throughout the cytoplasm of eukaryotic cells. It exists in two forms: rough ER (RER) and smooth ER (SER). The presence of ribosomes on the outer surface of the membrane distinguishes RER from SER. These ribosomes are involved in the synthesis of proteins, particularly those destined for secretion or insertion into membranes.
\n<\/section>\n
\nSmooth Endoplasmic Reticulum (SER) lacks ribosomes and is involved in lipid synthesis, detoxification, and calcium storage. Vesicles are often formed from the ER, but are not the defining characteristic of RER. The Golgi apparatus is a separate organelle involved in further processing and packaging of proteins and lipids synthesized in the ER.
