Answer:
d. have a great deal of rough endoplasmic reticulum reflecting the fact that they secrete a tremendous amount of protein (antibody)
Explanation:
Plasma cells are lymphocytes which originates from the bone marrow. They are B cells and not usually found in blood circulation. They tend to remain in organs of their choice.
Plasma cells mechanism of operation is by producing enough antibodies to fight against antigens it encounters in the bloodstream.
These antibodies are rich in protein which makes the plasma cells rich in rough endosplasmic reticulum. The rough endosplasmic reticulum is responsible for protein synthesis in cells.
This explanation validated the option D.
