Final answer:
Ribosomes are found in great abundance in cells such as muscle cells, nerve cells, and liver cells. They are necessary for energy production, signal transmission, and detoxification.
Step-by-step explanation:
Ribosomes are small organelles found in practically every cell and are responsible for protein synthesis. They are particularly abundant in cells that synthesize large amounts of protein. For example, the pancreas is responsible for creating several digestive enzymes and the cells that produce these enzymes contain many ribosomes. Thus, ribosomes would be found in great abundance in cells like muscle cells, nerve cells, and liver cells that require high protein synthesis for energy production, signal transmission, and detoxification, respectively.
