Question

Which of the following is NOT obtained from insects?
1. Silk
2. Honey
3. Lac
4. Pearl

Answer 1

Correct Answer - Option 4 : Pearl

The correct answer is Pearl.

• Silk is a natural protein fibre produced by the larvae of certain specific insects like caterpillars or moths.
• Honey is a sweet syrupy substance produced by honeybees from the nectar of flowers. When most of the water has evaporated from the honeycomb, the bee seals the comb with a secretion of liquid from its abdomen, which eventually hardens into beeswax.
• Lac is a natural resin of animal origin. It is secreted by an insect, known as lac-insect In order to obtain lac, these insects are cultured and the technique is called lac-culture.
• The formation of a natural pearl-
  • It begins when a foreign substance slips into the oyster between the mantle and the shell, which irritate­s the mantle.
  • It's kind of like the oyster getting a splinter.
  • The oyster's natural reaction is to cover up that irritant to protect itself.
  • The man­tle covers the irritant with layers of the same nacre substance that is used to create the shell.
  • This eventually forms a pearl.
