\nThe rough appearance of the Rough Endoplasmic Reticulum (RER) under a microscope is due to the presence of ribosomes attached to its cytoplasmic surface.
\n<\/section>\n
\n– The Endoplasmic Reticulum (ER) is a network of membranes throughout the cytoplasm.
\n– There are two types: Rough ER (RER) and Smooth ER (SER).
\n– Ribosomes are responsible for protein synthesis.
\n– Ribosomes can be free in the cytoplasm or attached to the ER membrane.
\n– The attachment of ribosomes gives the RER its characteristic “rough” appearance.
\n<\/section>\n
\nProteins synthesized on ribosomes attached to the RER are typically destined for secretion, insertion into cell membranes, or delivery to other organelles like lysosomes. The RER is involved in protein folding, modification, and transport. Centrioles are involved in cell division. Plastids (like chloroplasts) are involved in photosynthesis or storage. Lysosomes contain digestive enzymes. None of these attach to the ER to make it appear rough.
