Which one of the following would exocrine cells be expected to contain as a result of their function?
Correct answer: C. Both A and B
- A. Increased number of Golgi apparatus
- B. Increased amounts of rough endoplasmic reticulum (RER)
- C. Both A and B
- D. None
Explanation
Exocrine cells have a secretory function that involves the synthesis and processing of proteins and other molecules for export. The rough endoplasmic reticulum (RER) is responsible for the synthesis of proteins, and the Golgi apparatus processes and packages these proteins for secretion. Hence, both organelles are abundant in exocrine cells. Option C is correct because exocrine cells would be expected to have increased amounts of both the Golgi apparatus and RER. Option A is partially correct but incomplete, as it does not account for the role of the RER. Option B is also partially correct but does not include the Golgi apparatus. Option D is incorrect as it ignores the essential roles of both organelles in secretory cells.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
