__**Endoplasmic Reticulum**__

FACTS:
 * The endoplasmic recticulum is a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane.
 * While the function of the nucleus is to act as the cell brain, the endoplasmic reticulum functions as a packaging system.
 * The **endoplasmic reticulum** (**ER**) is an eukaryotic organelle.
 * There are two types of endoplasmic reticulum. (Rough ER,Smooth ER)
 * The surface of the rough endoplasmic reticulum (RER) is studded with protein-manufacturing ribosomes giving it a "rough" appearance.
 * The smooth endoplasmic reticulum (SER) consists of tubules and vesicles that branch forming a network.
