Diagram of the Golgi apparatus showing its stacked, curved membranes with labeled parts including cisternae, cis face, trans face, lumen, and various vesicles involved in cellular transport and secretion. — Golgi apparatus A membrane-bound organelle of eukaryotic cells, the Golgi apparatus is made up of a series of flattened, stacked pouches called cisternae that function as a series of compartments that progressively refine and direct cellular products to their proper destinations. .

Cytoplasmic microtubules provide essential structural support for the Golgi apparatus, helping to maintain the organization of its stacked cisternae.12

Beyond providing this physical framework, microtubules serve as critical tracks for the transport of materials to and from the organelle. Specifically, vesicles containing proteins and lipids migrate along these microtubule tracks through the cytoplasm to reach the Golgi apparatus. This movement is facilitated by motor proteins, such as kinesin and dynein, which utilize the energy of ATP hydrolysis to transport these membrane-bound vesicles to their destination.32
