The organelle that produces proteins is the ribosome. Ribosomes are the cell’s main protein-making machines, and the rough endoplasmic reticulum helps with making and processing proteins that are destined for transport or secretion.

  • Related organelles: The nucleus holds the DNA instructions, and the Golgi apparatus modifies and packages the proteins after they’re made.
