Q.12 Match cells of immune system in column-I and their functions in column-II and rewrite it. Column-IColumn-II (i) Cytotoxic T cells(a) Activation of helper T cells (ii) Plasma cells(b) Blood group antigens (iii) Antigen presenting cells(c) Secretion of perforins (iv) Red blood cells(d) Antibody production

Doubtly AI · Accepted Answer

Answer: (i) – (c), (ii) – (d), (iii) – (a), (iv) – (b). Column-IColumn-II (i) Cytotoxic T cells(c) Secretion of perforins (ii) Plasma cells(d) Antibody production (iii) Antigen presenting cells(a) Activation of helper T cells (iv) Red blood cells(b) Blood group antigens Cytotoxic T cells kill infected cells by releasing perforins that punch holes in their membranes; plasma cells (from activated B cells) secrete antibodies; antigen presenting cells (macrophages, dendritic cells) display processed antigen with MHC molecules and activate helper T cells; RBCs carry the A, B and Rh antigens on their surface.
