* Ribosomes: These are the sites of protein synthesis. They read the genetic code from messenger RNA (mRNA) and use that information to assemble amino acids into protein chains.

* Endoplasmic Reticulum (ER): This organelle is a network of membranes that plays a role in protein folding and modification. Some proteins are synthesized directly on the ER, while others are transported to the ER after being made on free ribosomes.
