What is the difference among smooth and rough endoplasmic reticulum?      

Ans) The endoplasmic reticulum is a fine membranous structure contiguous to the nuclear membrane and present in the cytoplasm. It develops an extense net of channels overall the cell and it is seperated in rough and smooth types.

The rough endoplasmic reticulum has huge quantity of ribosomes adhered to the external side of its membrane. The smooth endoplasmic reticulum does not have ribosomes attached to its membrane.

The major functions of the rough endoplasmic reticulum are synthesis and storage of proteins made in the ribosomes. The smooth endoplasmic reticulum plays a task in the lipid synthesis and, in muscle cells it is important in the conduction of the contraction stimulus.
