- Ribosomes - These are the non-membranous organs, also called as molecular machines of the living cell consisting of RNA and proteins.
- Golgi apparatus - They are the membranous organelles having infoldings on the membranes. They are responsible for transportation, packaging and in the formation of glycolipids and glycoproteins.
- Secondary wall - It is the structure like a wall and is present between the primary wall and the plasma membrane to separate them. Its function is elongation, support, strength etc.
- Endomembrane system - This is the outer membrane of various cell organelles and helps in the protection of cells from an outer environment, but other than that their function is not well known.
So, the correct option is 'Ribosomes - Non - membrane-bound and made up of RNA and proteins, Golgi apparatus - Important site for formation os glycolipids and glycoproteins, Secondary wall - Thin and capable of extension growth of cells, Endomembrane system - Function not co-ordinated'.
