The Endoplasmic Reticulum The endoplasmic reticulum (ER) is a network of flattened sacs and branching tubules that extends throughout the cytoplasm in plant and animal cells.
The endoplasmic reticulum is made up of membranous sacs and tubules. It has two different portions: the smooth endoplasmic reticulum and the rough endoplasmic reticulum. The rough endoplasmic reticulum is studded with ribosomes and produces proteins that are incorporated into cellular membranes outside of the cell. The smooth endoplasmic reticulum lacks ribosomes on its cytoplasmic surface.
