Open in App
Solution
The correct option is C Ribosome
Ribosomes are the cell organelles which are not bounded by any membrane are responsible for protein synthesis. They are made up of RNA and proteins. Nucleus is a double membrane bound part of cell which contains genetic material. Nucleoid is the term used for the naked single circular chromosome of prokaryotes which lie freely in the cytoplasm of cell. Nucleolus is a dense, rounded dark staining body inside nucleus and is without a limiting membrane. It also consists of RNA and proteins but its function is to synthesize and store RNA and also forms ribosomal subunits.Thus the correct answer is option C.
