producing progeny cells that include plasma cells and memory cells

Explanation:

B cells are the lymphocytes and are activated by helper T cells. When antigens enter the body, the active helper T cells make the B cells to undergo propagation. The B cells divide and give rise to plasma cells and memory cells. Plasma cells undergo further propagation to produce antibodies. The memory cells are the long-lived immune cells that stay in the body and mount a stronger immune response when the same antigen enters the body in the future.
