Final answer:
The question pertains to the classification of lymphocytes into B cells and T cells by examining their morphology and antigens. For lymphoma diagnosis, biopsy and immunohistochemistry are used. Lymphocytes are crucial for the immune response and are characterized by size and development in lymphatic tissues.
Step-by-step explanation:
The student's question revolves around identifying the classes of lymphocytes which are a specific type of leukocyte. There are two primary classes: B cells and T cells. Recognition of these cells involves differentiating them based on cellular morphology such as size and the nucleus-to-cytoplasm ratio, surface antigens, and biological functions. A simple table could be used to keep track of the varying leukocytes when examining blood smears under a microscope. In the case of lymphoma, a biopsy is examined, and immunohistochemistry may be used to determine the presence of specific cell-surface antigens, aiding in the diagnosis of the subtype of lymphoma.
Furthermore, the lymphocytes are described in terms of their formation, development, general percentages in blood, and size ranges.
