Liver cells manufacture glycoproteins, while adipose cells store fat. Which of the following subcellular structures is likely to be more prominent in liver cells than in adipose cells?

Cells that manufacture proteins must have a way to send the manufactured protein to their destinations. That is the job of the golgi apparatus, the distribution center of the cell.

Most cells have only one nucleus. The cytoskeleton and plasma membrane have no direct connection with fat storage or the manufacture of proteins.
