Ribosomes
Introduction and Functions
About
Ribosomes are organelles (organelles are the specialized parts of a cell that have unique jobs to perform) that have the important job of “synthesizing” or making proteins.
Functions
- They translate encoded information from the cell nucleus provided by messenger ribonucleic acid (mRNA)
- Link together amino acids selected and collected from the cytoplasm by transfer ribonucleic acid (tRNA). (The order in which the amino acids are linked together is determined by the mRNA)
- Export the polypeptide produced to the cytoplasm where it will form a functional protein.
The ribosomes are made in the nucleolus, a part of the nucleus. After ribosomes leave the nucleus, they can float freely around the cytoplasm, or attach to the rough endoplasmic reticulum (rER).

How do Ribosomes help a Cell Function?
Ribosomes make proteins that will be used within the cell itself. Proteins are needed for many cell functions such as repairing damage or directing chemical process.

Analogy
Ribosomes make us think of factories. Both of them produce something, and transport them to its final location.

Conclusion
Ribosomes are very important for the cell organism because they make proteins.
