The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Type of Cell**: - A plasma cell is a type of white blood cell (WBC) that is derived from B lymphocytes. 2. **Function of Plasma Cells**: - Plasma cells are primarily responsible for producing antibodies, which are crucial for the immune response. They do not produce antigens; instead, they respond to antigens by producing antibodies. 3. **Distinguish from Other Cells**: - It is important to differentiate plasma cells from other types of white blood cells. For example, basophils produce substances like heparin, histamine, and serotonin, which are involved in allergic reactions and inflammation. 4. **Clarification of Misconceptions**: - The statement that plasma cells produce heparin, histamine, or serotonin is incorrect. These substances are produced by basophils, not plasma cells. 5. **Conclusion**: - The correct characterization of plasma cells is that they are modified B lymphocytes of blood, which produce antibodies as part of the immune response. ### Final Answer: **Plasma cell**: A modified B lymphocyte of blood that produces antibodies.
