Ribosomes are structures inside the cells of certain types of organisms, including plants and animals. These structures can be loose in the cell or attached to the nuclear membrane or to the endoplasmic reticulum (another structure in the cell that is connected to the nuclear membrane, see link below for more information). When they are attached to the membrane or the endoplasmic reticulum, they can give those parts of the cell a "rough" or lumpy appearance. Ribosomes are round and are made up of two parts, which contain protein and RNA genetic material. They are responsible for protein synthesis (they make more protein) through chemical processes.
