Which term describes younger, immature neutrophils that are only beginning to develop lobes?

1. A neutrophil nucleus may have two to five lobes. 2. The number of lobes increases with the age of the cell. 3. Older, heavily lobed neutrophils are called polymorphonuclear cells, shortened to polys. 4. Younger cells that are only beginning to develop lobes are known as bands. 5. So polys sit at the mature end and bands at the immature end of the same lineage. 6. Blast cells are precursor forms named with the blast suffix earlier in the marrow sequence, not circulating neutrophils, which makes them the closest wrong answer. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 18 "The Cardiovascular System: Blood", section 18.4 Leukocytes and Platelets_
