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 free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum . Ribosomes exist in both eukaryotic and prokaryotic cells.

Explanation:
While examining the animal and plant cell through a microscope, you might have seen numerous organelles that work together to complete the cell activities. One of the essential cell organelles are ribosomes, which are in charge of protein synthesis.
The ribosome is a complex made of protein and RNA and which adds up to numerous million Daltons in size and assumes an important part in the course of decoding the genetic message reserved in the genome into protein.
The essential chemical step of protein synthesis is peptidyl transfer, that the developing or nascent peptide is moved from one tRNA molecule to the amino acid together with another tRNA. Amino acids are included in the developing polypeptide in line with the arrangement of codons of a mRNA. The ribosome, therefore, has necessary sites for one mRNA and no less than two tRNAs.
