i) Endoplasmic reticulum is a network of branching tubules that is involved in the protein and lipid synthesis of the cell.

ii) The Golgi complex is a system of membrane bound vesicles that functions in the storage and transportation of various biomolecules via its vesicles.

iii) The Golgi complex works in coordination with the endoplasmic reticulum.

iv) The bio molecules like proteins and lipids that are synthesized by the endoplasmic reticulum are transferred to the Golgi complex where they are processed, stored and then transported to the other parts of the cells where they are required.
