Group 10 Cell and Molecular Biology Module Homework 3 1. A T cell is a lymphocyte that matures in the thymus. Different T cells have different functions and are essential for a working immune system. Two kinds of T cells are cytotoxic T cells and helper T cells. Helper T cells activate and direct other immune cells, and cytotoxic T cells kill infected cells or other pathogens 2.
