4. Ribosomes are tiny glanular structures that are either floating freely in cytoplasm or are bound to endoplasmic reticulum.

5. Translation.

6. Eukaryotic ribosomes are ten times larger than prokaryotic ones.

7. Not sure about this. But they are necessary for protein synthesis as they assemble amino acids into protein chains.

8. Ribosomal RNA is part of ribosome. These complex structures catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for proteins.

9. When a ribosome is not working, it disassembles into two smaller units.
