Textbook Question

The blood cell that can become an antibody-secreting cell is:
a. Lymphocyte
b. Megakaryocyte
c. Neutrophil
d. Basophil

Verified step by step guidance

Understand the role of antibodies in the immune system: Antibodies are proteins produced by certain immune cells to identify and neutralize pathogens like bacteria and viruses.

Recall the type of blood cell responsible for producing antibodies: Antibodies are secreted by plasma cells, which are derived from a specific type of white blood cell.

Identify the precursor to plasma cells: Plasma cells originate from B lymphocytes (a subtype of lymphocytes). When B lymphocytes are activated by an antigen, they differentiate into plasma cells that secrete antibodies.

Eliminate incorrect options: Megakaryocytes are involved in platelet production, neutrophils are phagocytic cells that engulf pathogens, and basophils release histamine during allergic reactions. None of these are involved in antibody production.

Conclude that the correct answer is 'Lymphocyte,' as B lymphocytes are the cells that can become antibody-secreting plasma cells.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Lymphocytes

Lymphocytes are a type of white blood cell that play a crucial role in the immune system. They are primarily responsible for the adaptive immune response, which includes the production of antibodies. B lymphocytes, a subtype of lymphocytes, can differentiate into plasma cells that secrete antibodies to neutralize pathogens.

Antibodies

Antibodies are specialized proteins produced by B cells in response to antigens, which are foreign substances like bacteria and viruses. Each antibody is specific to a particular antigen, allowing the immune system to target and eliminate pathogens effectively. The ability of lymphocytes to produce antibodies is essential for long-term immunity.

Hematopoiesis

Hematopoiesis is the process of blood cell formation that occurs in the bone marrow. It involves the differentiation of stem cells into various types of blood cells, including lymphocytes, neutrophils, and megakaryocytes. Understanding hematopoiesis is vital for comprehending how different blood cells, including those involved in immune responses, are generated.
