Ribosomes are tiny but very important parts of all living cells. They are like little machines that help make proteins. Think of them as workers that read the genetic instructions found in a special kind of RNA called messenger RNA (mRNA).

Types of Ribosomes:

1. Free Ribosomes: These float around in the cell's liquid part, called the cytoplasm. They make proteins that the cell uses for its own needs.
2. Bound Ribosomes: These are attached to a structure called the endoplasmic reticulum (ER). They make proteins that the cell can send out or use in its outer layer.

Role in Protein Synthesis:

1. mRNA Delivery: Ribosomes hold onto the mRNA and help turn its special code into a sequence of building blocks called amino acids.
2. Amino Acids: The ribosomes connect these amino acids together to create longer chains called polypeptides, which then fold to become functional proteins.

In short, ribosomes play a key role in turning genetic information into proteins. These proteins are important because they help carry out many jobs in the cell!
