Stomach cells have a large quantity of ribosomes and Golgi apparatus because they are actively involved in the production and secretion of digestive enzymes and other proteins necessary for the breakdown of food.

Here's a breakdown:

* Ribosomes: These are the protein factories of the cell. They translate the genetic code from mRNA into proteins. Stomach cells require a high number of ribosomes to synthesize a large amount of digestive enzymes like pepsin, gastric lipase, and other proteins essential for digestion.

* Golgi Apparatus: This organelle acts like a processing and packaging center. It receives proteins synthesized by ribosomes, modifies them, sorts them, and packages them into secretory vesicles. These vesicles then transport the enzymes to the stomach lumen where they are released to break down food.

In summary:

The high number of ribosomes and Golgi apparatus in stomach cells ensures efficient production, modification, and secretion of digestive enzymes, enabling them to effectively perform their role in the breakdown of food.
