In biology, the endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the eukaryotic cell, cytoplasm and serves multiple functions, especially in protein synthesis, folding, modification and transporting proteins. An endoplasmic reticulum (ER) retains all eukaryotic cells.
