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.
Plant cell do have ribosomes and they are composed of proteins and ribosomal RNA. The ribosomes in a plant cell are found in the cytoplasm, the surface of the rough e ndoplasmic reticulum, the mitochondria and on chloroplasts. There are two types of ribosomes-free ribsomes and attached ribosomes.The a ttached ribosomes are bound to the surface of the endoplasmic reticulum and they are the site for protei n synthesis. Synthesis of proteins also occurs in the free ribosomes.lant cell do have ribosomes and they are composed of proteins and ribosomal RNA.
