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 a membrane system of folded sacs and interconnected channels that serves as a site for protein and lipid synthesis. The various folds of the endoplasmic reticulum provide a large surface where cellular functions can take place. There are two types of endoplasmic reticulum: smooth and rough. Rough endoplasmic reticulum is a form of endoplasmic reticulum that is studded with ribosomes. Since it has ribosomes stuck all over it, it has a bumpy appearance and is therefore called rough endoplasmic reticulum.
