There are two different locations where ribosomes can be found in a  cell. These two locations are suspended in the cytosol and attached  to the endoplasmic reticulum.
The polypeptide chain is released and the ribosome subunits are returned to the pool of ribosome units in the cytoplasm. Ribosomes are found in two locations in the cell. Free ribosomes are dispersed throughout the cytoplasm. Bound ribosomes are attached to a membranous structure called the endoplasmic reticulum.ound throughout the cell, ribosomes are composed of ribosomal ribonucleic acid (rRNA) and proteins. They are the sites of protein synthesis. Although Robert Hooke first used a light microscope to look at cells in 1665, it was only during the last few decades that the cell's organelles were discovered.
