Nucleus
Most cells have a single nucleus; however, as seen in this blood smear, mature red blood cells are unique in that they have no nucleus. Also present are much less numerous white blood cells, which can have a variety of nuclear shapes. The two white blood cells, polymorphonuclear neutrophils (PMNs), seen here have multi-lobed nuclei. 1000x
