Question

Match the cells in Column I with their primary function in Column II. 

 

• A. A-2, B-1, C-3, D-4
• B. A-3, B-2, C-1, D-4
• C. A-2, B-3, C-1, D-4
• D. A-4, B-1, C-3, D-2

Hint:

Create a quick reference table for immune cells and their defining functions or markers. Associating "Plasma" with "Antibodies" and "CD8" with "Cytotoxic" will help you quickly solve matching questions.

Answer 1

The Correct Option is A

To correctly match the cells in Column I with their primary functions in Column II, we need to understand the role each cell type plays in the immune response. Here's a detailed explanation:

1. Plasma cells:
   • Function: Plasma cells are responsible for antibody secretion.
   • Explanation: These cells are differentiated B-cells that produce large volumes of antibodies, which help neutralize pathogens.
2. CD8⁺ T cells:
   • Function: CD8⁺ T cells are involved in cytotoxic killing.
   • Explanation: These cells, also known as cytotoxic T lymphocytes, destroy virus-infected cells and cancer cells by inducing apoptosis.
3. Dendritic cells:
   • Function: Dendritic cells are key players in antigen presentation.
   • Explanation: Acting as antigen-presenting cells, they process antigen material and present it on their surface to T cells, initiating an immune response.
4. Mast cells:
   • Function: Mast cells primarily cause histamine release.
   • Explanation: These cells play a significant role in allergic reactions and inflammation by releasing histamine and other chemicals.

Conclusion: Based on the above explanations, the correct matches are:

A-2, B-1, C-3, D-4
