Final answer:
The correct answer is that plasma cells are terminal and dedicated to producing immunoglobulin. They are derived from activated B cells and focus solely on antibody production until they die. The correct option is e) They are terminal and dedicated to producing immunoglobulin.
Step-by-step explanation:
The true statement regarding plasma cells is e that they are terminal and dedicated to producing immunoglobulin. Plasma cells are derived from B cells once they have been activated. These cells undergo a differentiation process where their main function becomes the production of antibodies, or immunoglobulins, at an impressive rate.
Plasma cells do not have surface receptors for antigens, as those are characteristics of undifferentiated B cells. Moreover, they do not undergo somatic hypermutation or differentiate into memory B cells.
Instead, they are terminally differentiated cells meaning that they have reached the end of their development pathway and are engaged solely in antibody production. The correct option is e) They are terminal and dedicated to producing immunoglobulin.
