The Golgi apparatus is a crucial organelle within the cytoplasm of eukaryotic cells, playing a central role in the processing, sorting, and packaging of biological molecules. Structurally, it consists of a series of flattened membrane sacs, known as cisternae, which are organized into distinct stacks. Proteins and lipids synthesized in earlier cellular compartments arrive at the *cis* face, where they undergo modification and initial sorting. As these materials traverse the stack toward the *trans* face, they are further processed and packaged into vesicles. This final step allows the cell to efficiently direct macromolecules to their proper destinations, whether they are to be incorporated into the plasma membrane, secreted outside the cell, or delivered to other internal organelles like lysosomes.
