The cells in the human body that you would expect to have a lot of Golgi apparatus are secretory cells, such as those found in glands like the pancreas and salivary glands, as well as plasma cells that produce antibodies.
The Golgi apparatus is crucial for processing and packaging proteins and lipids that are synthesized in the endoplasmic reticulum. In secretory cells, the Golgi takes these newly made molecules and modifies them, preparing them for secretion or for use within the cell. For instance, in the pancreas, the Golgi apparatus plays an essential role in producing digestive enzymes that need to be released into the digestive tract.
Additionally, plasma cells, which are derived from B cells of the immune system, are responsible for producing large quantities of antibodies. The Golgi apparatus in these cells is very active in processing and secreting these antibodies to fight infections.
In summary, cells that are heavily involved in secretion and production of proteins will have a more extensive Golgi apparatus due to their high demand for sorting and processing different types of biomolecules.
