The endoplasmic reticulum is a fragile membranous structure contiguous to nuclear membrane and present in cytoplasm. It forms an extensive net of channels throughout cell and is categorized in smooth or rough types.

The rough endoplasmic reticulum has a high number of ribosome which is attached to the external side of membrane. The smooth endoplasmic reticulum doesn’t have ribosome attached to its membrane.

The main roles of rough endoplasmic reticulum storage are and synthesis of proteins made in ribosome. The smooth endoplasmic reticulum plays a role in lipid synthesis and, in muscle cells; it is significant in the conduction of contraction stimulus.
