Answer: Proteins.
Explanation:
Ribosomes are cellular organelles, the protein builders the cell. They link amino acids together in the order specified by the genetic material, so the result is a long chain of amino acids that form a protein. Free ribosomes found in the cytoplasm are important because they produce proteins which are essential for internal cellular activity.
The advantage of having a high density of ribosomes working at the same time is speed, as proteins are made one after another. Then, the more ribosomes there are, the more proteins there will be.
