The organelle that makes ribosomes is the nucleolus.

Quick Scoop

  • In eukaryotic cells, the nucleolus is a dense region inside the nucleus where ribosomal RNA (rRNA) is made and combined with proteins to form ribosomal subunits.
  • These ribosomal subunits then leave the nucleus through nuclear pores and come together in the cytoplasm to form working ribosomes for protein synthesis.
  • The nucleolus is sometimes described as a ribosome “factory” because it is specialized for large‑scale ribosome production.

So, if you’re ever asked “what organelle makes ribosomes?”, the precise answer is: the nucleolus inside the nucleus.
