Nucleolus
In biology, the nucleolus is, strictly speaking, a "suborganelle" of the cell nucleus, which is an organelle.

Nucleolus
The nucleolus is a structure within the nucleus where the ribosomal subunits are produced.
In cells that have been stained, it appears darker than the nucleus.

The Nucleolus
During the period between cell divisions, when the chromosomes are in their extended state, 1 or more of them (10 in human cells) have loops extending into a spherical mass called the nucleolus.

Telophase
a new set of nucleolus forms along with the nuclear membrane as well as the nucleolus
the cell plate appears and begins to slip in two while the spindle fibers fade and the chromosomes uncoil so the cell can make proteins.

The chromosomal region around which the nucleolus forms, a site of tandem repeats of the rRNA gene. A region (or regions) of the chromosome set physically associated with the nucleolus and containing rRNA genes.
