B and T lymphocytes arise from _____________

  • A.hematopoietic stem cells
  • B.germ cells
  • C.somatic cells
  • D.spermatocytes

Answer: A

Correct answer: hematopoietic stem cells

Both arise from the haematopoietic stem cells of the bone marrow. B cells complete their maturation there; T cells migrate to the thymus to mature, which is what the T stands for. Germ cells give rise to gametes, and have nothing to do with it.
