Lymphocyte
Lymphocytes are small, spherical cells with rounded, highly heterochromatic nuclei and minimal cytoplasm. Lymphocytes are agranular white blood cells transported via the blood, but are active only after entering connective tissue. Lymphocytes function in the immune response and are classified as either T or B lymphocytes. B lymphocytes differentiate into plasma cells that produce antibodies. B and T lymphocytes can only be distinguished with immunohistochemical staining methods. 1000x, 7000x

A lymphocyte has a distinct, heterochromatic, spherical nucleus and no cytoplasmic granules. This particular lymphocyte has a moderate amount of cytoplasm with organelles, and thus could either be a medium lymphocyte or a B lymphocyte which is beginning its transformation into a plasma cell.
