Q. Which of the following is NOT obtained from insects?
- Silk
- Honey
- Lac
- Pearl
Answer: Pearl
- Silk that is made by the silk worm is made up of two main proteins, sericin and fibroin.
- Honey is a sweet, viscous food substance produced by bees and some related insects. Bees produce honey from the sugarysecretions of plants (floral nectar) or from secretions of other insects such as honeydew).
- Lac is the scarlet resinous secretion of a number of species of lac insects, of which the most commonly cultivated is Kerria lacca.
A pearl is a hard glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as a conulariid.
