Respuesta :
The endoplasmic reticulum is a network of membranes originating at the nuclear envelope and winding through the cell.
What is endoplasmic reticulum?
The endoplasmic reticulum (ER), which also performs numerous other critical tasks like folding proteins, is essentially the eukaryotic cell's transportation system. Rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum are the two subunits that make up this particular sort of organelle (SER).
Most eukaryotic cells have the endoplasmic reticulum, which organizes itself into a network of tubular structures in the SER and flattened, membrane-enclosed sacs known as cisternae in the RER. The outer nuclear membrane and the ER's membranes are one and the same. Spermatozoa and red blood cells do not contain the endoplasmic reticulum.
