False-colour transmission electron micrograph of part of a pancreatic cell,showing rough endoplasmic reticulum (pink & white parallel,linear structures) and part of the cell's nucleus (upper left). The endoplasmic reticulum (ER) is a complicated system of membranes which forms a network of flattened cisternae (cavities) through- out the cytoplasm. These function as reservoirs and channels for the storage and transport of proteins and lipids. Rough ER is coated in tiny protein-synthesising particles known as ribosomes,and is,in general,responsible for the synthesis of proteins destined for secretion by the cell.
