Which organelles are small granules that help the cell make proteins and may be attached to the Endoplasmic Reticulum?

Explanation:
Ribosomes are the tiny granules that drive protein production. They translate messenger RNA into polypeptides, and they can float freely in the cytoplasm or attach to the rough endoplasmic reticulum, where their presence gives the ER its rough texture and enables synthesis of proteins destined for secretion or membranes. The nucleus stores DNA and handles transcription, not the actual assembly of proteins, so it isn’t described as small granules involved in protein synthesis. Lysosomes and peroxisomes handle digestion and metabolic reactions, not protein assembly, so they don’t fit this role.
