Ribosomes aren't organelles. They are just really large, composite, macromolecules that are composed of RNA and proteins.


They are synthesized by genes (multiple genes) for the rRNA and the different proteins. They don't have a lipid bilayer, don't compartmentalize anything - they are just a large structure that is composed of a variety of gene products (lots of ribosomal proteins, as well as strands of rRNA, which is the enzymatic component). They are essentially really large enzymes.
