Which of the following is a naturally occurring polymer?
- A. Polystyrene
- B. Cellulose
- C. Nylon
- D. Teflon
Explanation
Cellulose is a natural condensation polymer of beta glucose and is the main structural material of plant cell walls, as are starch, proteins, natural rubber and DNA among natural polymers. Polystyrene, nylon and teflon are all synthetic. Recognising that natural polymers vastly outnumber synthetic ones in the living world is the point of the question.
