A ribosome is a cellular organelle involved in protein synthesis. They are found free floating in the cytoplasm (free ribosomes) or attached to the Endoplasmic Reticulum (bound ribosomes.) The part of the Endoplasmic Reticulum which has ribosomes attached to it is called the Rough Endoplasmic Reticulum.

A ribosome is an organelle in cells that assembles proteins. Ribosomes are composed of ribosomal RNA and ribosomal proteins (known as a Ribonucleoprotein or RNP). It translates Messenger RNA (mRNA) into a polypeptide chain (e.g., a protein). It can be thought of as a factory that builds a protein from a set of genetic instructions. Ribosomes can float freely in the cytoplasm (the internal fluid of the cell) or bind to the endoplasmic reticulum, or to the nuclear envelope. Since ribosomes are ribozymes, it is thought that they might be remnants of the RNA world

Ribosomes are cytoplasmic granules composed of RNA and protein, at which protein synthesis takes place

Ah I remember that from my biology class.
