Here's why:
* Ribosomes are not organelles: They are complex molecular machines responsible for protein synthesis, but they lack the membrane-bound structure that defines organelles.
* Components of ribosomes: Ribosomes consist of two subunits: a large subunit and a small subunit. These subunits are composed of ribosomal RNA (rRNA) and proteins.
Therefore, the two things that make up ribosomes are rRNA and proteins.
