Final answer:
Ribosomes are organelles that function as protein factories in cells, involved in protein synthesis by assembling amino acids into proteins.
Step-by-step explanation:
Ribosomes are cellular organelles that function as protein factories in cells. They are involved in the process of protein synthesis, where they read the messenger RNA (mRNA) molecules and use the information encoded in them to assemble amino acids into proteins. Ribosomes can be found freely floating in the cytoplasm or attached to the endoplasmic reticulum.
