Ribosomes and golgi bodies will be most numerous in the cells of salivary glands.
Ribosomes are the cell organelles that are associated with the production of proteins by the process of translation from mRNAs. Golgi bodies are the organelles that are associated with the secretion of the secretory vesicles outside the cells.
Salivary amylase is an enzyme and all the enzymes are proteins. They are needed to be translated by ribosomes from the mRNAs. And as they are produced, they are needed to be secreted outside the cell. So golgi bodies and ribosomes are found most numerously inside the salivary gland cells.
