2. Description:
•Discovered and named ribosome by Palade so called Palade particle
•Also called engine of cell/ protein factory of the cell
•Smallest,unmembranous ,electron microscopic
•Made of up RNA & protein
•It is formed inside Nucleolus

3. Function:
Ribosome helps in protein synthesis.

4. Types of Ribosome:
70s ribosome
Prokaryotic cell
Eukaryotic cell
Mitochondria
Chloroplast
Sub-units
30s –has single r-RNA
50s – has two r-RNA

5. 80s Ribosome:
•Found in eukaryotic
Free – synthesize non secretor non export protein
RER- synthesize secretor export protein
Sub-units
