The main function of the Golgi apparatus in a plant cell is to modify, package, and transport proteins and lipids received from the endoplasmic reticulum. Additionally, in plant cells, the Golgi apparatus plays a crucial role in the synthesis of complex polysaccharides that are a major component of the plant cell wall. These polysaccharides are then transported to the cell surface for cell wall construction. The Golgi apparatus also sorts proteins and polysaccharides for delivery to various destinations within the cell, including secretion and vacuole targeting.
