1.	Silk is obtained from which of the following stages of the Silk moth ?1. Pupa2. Adult3. Larva4. Caterpillar
Answer» Correct Answer - Option 1 : Pupa The correct answer is Pupa. Female silk moth lays eggs and then the larvae are hatched out of eggs known as caterpillars. They are grown in size and they enter the second stage called pupa where they secrete fibre made up of preteen which when comes in contact with air and it hardens to become silk fibre. After this, the caterpillar completely covers itself by the fibre and turns into a pupa. This covering is called a cocoon. Silk is a natural protein fibre, some forms of which can be woven into textiles. The protein fibre of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colours.
