What do ribosomes do?

Answer:

Ribosomes are organelles that synthesize proteins for the cell and send protein to the nucleus. Ribosomes can be free floating in the cytoplasm, or can be attached to the outer surfaces of the rough endoplasmic reticulum and are known as bound ribosomes. They use amino acids to create the protein when the nucleus sends out messenger RNA to "tell" the ribosomes to make the protein.
