Plasma B-cells produce antibodies, T-cells do not destroy pathogens by phagocytosis, and T-cells mature in the thymus, not the red bone marrow.
Plasma B-cells produce antibodies: B cells mature in the bone marrow and produce antibodies known as immunoglobulins, which are key components of adaptive immunity.
T-cells destroy pathogens by phagocytosis: T cells do not destroy pathogens by phagocytosis. Instead, they target and destroy cells infected with intracellular pathogens through cell-mediated immunity.
T-cells mature in the red bone marrow: T cells actually mature in the thymus, not in the red bone marrow. The thymus is where T cells undergo maturation and differentiation.
