CELL ATLAS questions and answers with solutions 2024 Lymphoblast - ANSWER 10 -20 microns; Round to oval nucleus with fine, evenly stained chromatin structure, 1 -2 nucleoles; Blue cytoplasm with clear zone closest to the nucleus; No granules Prolymphocyte - ANSWER 10 -20 microns; Round nucleus, somewhat looser structure than the lymphoblast. One (1) distinct nucleoli; Blue cytoplasm; No granules Small Lymphocyte - ANSWER 7 -8 microns; Round to oval nucleus, condensed chromatin structure. No nucleoles. Narrow basophilic (light or dark blue) cytoplasm band; Few bright violet granules Large Lymphocyte - ANSWER 9 -15 microns; Oval/bulging nucleus, somewhat looser chromatin structure than small lymphocyte. No nucleoles; Plentiful colorless to light blue cytoplasm; Few bright violet granules Plasma Cell - ANSWER 7 -15 microns; Round nucleus, eccentrically placed. Compact (radial) chromatin structure; Dark blue cytoplasm with perinuclear zone (sometimes vacuoles) Lymphoblast, Prolymphocyte, Small Lymphocyte, Large Lymphocyte, Plasma Cell - ANSWER LYMPHOPOEISIS Megakaryoblast - ANSWER The cell that gives rise to the megakaryocyte is the megakaryoblast, which is difficult to identify morphologically Megakaryocyte - ANSWER 25 -90 microns; Round, irregular cell wall; Nucleus with 2 -16 lobes. The size of the cell varies according to number of lobes. Finely dispersed chromatin mesh in the nucleus. Small nucleoles may be present. Blue to pink cytoplasm Thrombocytes - ANSWER 1 -15 micron; Cytoplasm fragment of the megakaryocyte; Light blue to colorless cytoplasm; Scattered red granules Megakaryoblast, Megakaryocyte, Thrombocytes - ANSWER MEGAKARYOPOIESIS
