Worked Solution & Example Answer:(a) Identify ONE type of T lymphocyte - HSC - SSCE Biology - Question 20 - 2004 - Paper 1
Step 1
Step 2
Distinguish between the functions of B cells and T cells.
Answer
B cells primarily function in the production of antibodies, which are essential for targeting and neutralizing pathogens. They play a crucial role in the humoral immune response.
In contrast, T cells are involved in cell-mediated immunity. They regulate immune responses and kill infected host cells directly, particularly through the activity of Cytotoxic T cells. Additionally, Helper T cells assist in activating B cells and enhancing the immune response.
