Question

Name the two types of lymphocytes and write one difference between the two.

Answer 1

Although all lymphocytes originate from only one type of stem cell, the final steps in their development lead to the production of two distinct types of lymphocyte: T-lymphocytes and B-lymphocytes.

T-lymphocytes	B-lymphocytes
Produced in the bone marrow and migrate to the thymus gland for final maturation.	Produced in the bone marrow and mature in the bone marrow itself.
If the antigen comes from outside the body, it needs to be presented to the T-cells on the surface of an antigen presenting cell.	Recognize and bind antigen particles without having to be presented by an antigen presenting cell.
Cell- mediated immunity	Antibody mediated (humoral) immunity
