Answer 2

Formation of Cocoon:-

• A cocoon is a covering made by silk moths and other insects as a part of their life cycle to protect the pupa.
• Cocoon made by silk moth can be used for the production of silk fibres by killing the insect inside the cocoon using boiling water
• The silkworms secretes a very fine filament made of fibroin protein from two glands on its head which solidifies upon exposure to air and becomes silk fibres.
• Through movement of head from side to side in the form of figure of eight, the silkworm completely covers itself forming the cocoon.
