 Ribosomes CBSE Class 11: MCQs, Case Study & Assertion Reason Questions  Structure and function of ribosomes showing 70S and 80S subunits involved in protein synthesis.   - Dr.Sanjaykumar Pawar  Ribosomes  1. What are Ribosomes? Ribosomes are tiny granular (grain-like) structures present inside cells. They were first observed under an electron microscope. They were discovered by in 1953 . Under the electron microscope, they appear as dense particles. 2. Composition of Ribosomes Ribosomes are made up of: Ribosomal RNA (rRNA) Proteins Therefore, ribosomes are ribonucleoprotein particles . 3. Membrane Around Ribosomes Ribosomes are not surrounded by any membrane . Hence, they are called non-membranous cell organelles . 4. Function of Ribosomes Ribosomes are the site of protein synthesis . They help in translating genetic information into proteins. Therefore, ribosomes are known as the "Protein Factories of the Cell." Types of Ribos...
