n.
A structure composed of RNA and protein, present in large numbers in the cytoplasm of living cells and serving as the site for assembly of polypeptides encoded by messenger RNA.

ribosome

(ˈraɪbəˌsəʊm)
n
(Biochemistry) any of numerous minute particles in the cytoplasm of cells, either free or attached to the endoplasmic reticulum, that contain RNA and protein and are the site of protein synthesis
[C20: from ribo(nucleic acid) + -some3]
ˌriboˈsomal adj

ri•bo•some

(ˈraɪ bəˌsoʊm)

n.
a tiny, mitten-shaped organelle occurring in great numbers in the cell cytoplasm and functioning as the site of protein manufacture.

ri·bo·some

(rī′bə-sōm′)
A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are often attached to the membrane of the endoplasmic reticulum. See more at cell.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.ribosome - an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell; "the ribosome is the site of protein synthesis"
cell organ, cell organelle, organelle - a specialized part of a cell; analogous to an organ; "the first organelle to be identified was the nucleus"

Known as the cells protein "factory," the ribosome "translates" what are called "amino acids"-think of phrases in a sentence-into proteins that play vital functions in the human body, from twitching the muscles and sending out signals to digesting food and providing structure for hair and bone.
