Cytoplasmic organelles at which proteins are synthesized.

Explanation:
Protein synthesis is carried out by ribosomes, the RNA–protein machines that read messenger RNA and assemble amino acids into polypeptides. They can float freely in the cytoplasm or be attached to the rough endoplasmic reticulum, forming rough ER. The Golgi apparatus processes and packages proteins after synthesis, the nucleus is where transcription occurs to make mRNA, and mitochondria have their own ribosomes for a small set of proteins but do not handle most cytoplasmic synthesis. So, the cytoplasmic sites where protein synthesis occurs are the ribosomes.
