Question

Which of the following produce antibodies?

• A. Macrophages
• B. Mast cells
• C. Lymphocytes
• D. Fibroblasts

Answer 1

The correct option is C

Lymphocytes

The correct option is C.

Explanation of the correct answer:

1. Lymphocytes are agranulocytes (WBC).
2. When pathogens enter our body or antigens are introduced in our body lymphocyte cells produce antibodies.
3. Lymphocytes are the plasma cells that help in producing antibodies.
4. Antibodies act against these antigens or pathogens.
5. There are two kinds of lymphocytes T-lymphocytes and B-lymphocytes.
6. B-lymphocytes are related to humoral immunity.
7. B-lymphocytes produce antibodies in blood plasma.
8. These antibodies are gamma globulins.
9. When an antigen binds with lymphocytes, activated B lymphocytes are formed.
10. Activated B lymphocytes are antibodies.
11. T-lymphocytes are related to cell-mediated immunity.
12. T-lymphocytes are stimulated by pathogens like fungus, viruses or protozoans.
13. T-lymphocytes multiplicate and convert in lymphoblast and secrete lymphokine.

Explanation of the incorrect options:

Option A:

1. Macrophages function by detecting, engulfing, and destroying pathogens and apoptotic cells.

Option B:

1. Mast cells maintain homeostasis in the immune system.
2. They are present in the skin and mucosa.
3. Thus, they are the first line of defense.

Option D:

1. Fibroblasts maintain the structural framework of tissues.

Final answer: Lymphocytes produce antibodies.
