Question

How is silk obtained from silk worm ? Explain.

Answer 1

Female silk worm lays eggs on mulberry leaves. These eggs hatch into caterpillar or larvae. Larvae develop by eating leaves of this plant. Caterpillars form a thread structure (cocoon) around themselves . In cocoon , caterpillar changes to pupa stage. Before the cocoon changes to adult , it is kept in sun or hot water or steam to obtain silk.
