Concerning lymphocytes,

Question

Quizplus · Accepted Answer

Small groups of identical B cells or T cells, called clones, are produced during adaptive immunity. This is because during the process of adaptive immunity, B and T cells undergo clonal selection and expansion, where the immune system selects and activates only those lymphocytes that recognize the specific antigen presented. This leads to the production of a large number of identical clones that can then target and destroy the antigen. Option A is incorrect because in adults, there are usually more B cells than T cells in the blood. Option B is incorrect because pre-B cells are derived from stem cells in adult red bone marrow, while pre-T cells are derived from stem cells in the bone marrow but mature in the thymus gland. Option D is incorrect because not all lymphocytes synthesize and secrete antibodies - only B cells do. Option E is incorrect because lymphocytes do have properties, and the other options describe some of them.
