What are the dark blobs attached to the Golgi body?

The dark blobs attached to the Golgi body are typically associated with ribosomes, which are involved in protein synthesis. In some contexts, they may also represent vesicles that transport proteins and lipids to and from the Golgi apparatus during the processes of secretion and modification. These structures can appear as dense spots under an electron microscope due to their high content of macromolecules.
