A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum. The outer surface of the endoplasmic reticulum can be smooth or rough
The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER)
Explanation:
SER :- Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell.
RER :- The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins.

Verified answer
endoplasmic reticulum(ER) is network like structure present between nucleus and plasma membrane
Explanation:
There are two types of endoplasmic reticulum-
1) Rough Endoplasmic Reticulum (RER)
They are studded with ribosomes
Function -
• Synthesis protein
2) Smooth Endoplasmic Reticulum (SER)
They are not studded with ribosome
Function-
• Synthesis lipid/fat
• detoxify drugs/poison in liver cells (vertebrate).
