Morphology
nucleolus + organizer
The compound is compositional: 'nucleolus' (the ribosome-producing structure) + 'organizer' (something that organizes or causes formation) yields the idea of an entity that organizes or creates the nucleolus. Although the precise biological locus (a chromosomal region) is specialized domain knowledge, the basic function is directly derivable from the constituents, so learners who know both words can infer the core meaning.
Etymology
Nucleolus organizer comes from the picture of a small manager on a chromosome: the word nucleolus names the cell part and organizer suggests it 'organizes' the pieces needed to build that part. So the name refers to the chromosome region that 'organizes' and helps make the nucleolus after the cell divides.
