What cellular structure is found to be expanded in plasma cells,but not in their precursor cells?
A)nuclei
B)mitochondria
C)chloroplasts
D)rough endoplasmic reticulum
E)lysosomes

Question

Quizplus · Accepted Answer

The rough endoplasmic reticulum (RER) is a cellular structure involved in protein synthesis and modification. Plasma cells are specialized B cells that secrete large amounts of antibodies. To deal with this high secretory demand, they have an expanded RER compared to their precursor cells. The other structures listed (nuclei, mitochondria, chloroplasts, lysosomes) are not specifically expanded in plasma cells.
