where ribosomes are made
Nucleolus.
Yes. I suspect you mean "nucleus" (presumably of an atom, not a cell), not "nucleolus" (a strictly biology term), but either way the answer is still yes.
The dark-staining, spherical body in the nucleus that produces ribosomal subunits is called nucleolus. It is composed of proteins and ribonucleic acids.
It's called a nucleolus
Do you mean nucleolus? If so, all Eukaryotic cells like plant and animal cells have a nucleolus. but most bacterial cells such as Prokaryotes have a nucleoid which is different from a nucleus or nucleolus.

The nucleolus is not a plant, but an organelle within the nucleus of a cell. The nucleolus transcribes and assembles RNA.
