What are the similarities between Golgi apparatus and endoplasmic reticulum?

Golgi apparatus and endoplasmic reticulum are two essential cell organelles found in eukaryotic cells. They form two important components of the endomembrane system of the cell. While they are distinctly different from one another, there are several similarities between these two organelles.

• Both are vital cell organelles
• Both are involved in the formation of the cell’s endomembrane system
• Both are present only in eukaryotic cells
• Both are membrane-bound
• Both contain a network of flattened, fluid-filled sacs called cisternae, which are membrane-enclosed
• Both play roles in protein maturation
• Both are capable of forming transport vesicles
• Lipid metabolism occurs in Golgi apparatus and smooth ER
