Ribosomes are organelles composed of RNA molecules and proteins that carry out the process of protein synthesis. They can be found in cells.
In eukaryotic cells, they can be found attached to the rough endoplasmic reticulum or floating in the cytoplasm. While in bacteria, all ribosomes are free floating.

This is because eukaryotic cells have a more complex structure and have organelles like the endoplasmic reticulum, which provides a surface for ribosomes to attach to. Bacteria, on the other hand, do not have organelles like the endoplasmic reticulum and therefore all their ribosomes are free floating in the cytoplasm.
