Exam answer
LYMPHOCYTES (B-lymphocytes).
Explanation
Lymphocytes produce ANTIBODIES — proteins that lock onto a specific antigen and neutralise it or mark it for destruction.
THE DISTINCTION BEING TESTED, and it is the point of asking both parts together: NEUTROPHILS fight by ENGULFING — a direct, physical attack, effective against anything. LYMPHOCYTES fight by PRODUCING ANTIBODIES — a chemical, SPECIFIC attack, each antibody matching one antigen.
Because antibodies are specific and are remembered after the first exposure, lymphocytes are the basis of IMMUNITY and of how vaccination works.
