Silk originates from the cocoon produced by which organism?

• A. Bees
• B. Spiders
• C. Silkworms
• D. Cocoon (Silk Worm)

Answer: (D)

Silk fibers come from the cocoon spun by silkworm larvae. The silkworm secretes a protein-rich thread from its salivary glands and wraps it around itself to form a continuous cocoon that protects it during metamorphosis. This cocoon is then processed to extract the silk filament, which is the material used to make silk textiles. Spider silk exists, but it is produced for webs and other uses, not as a cocoon for metamorphosis in the way silkworm cocoons are. Bees do not produce silk cocoons. So the organism responsible for silk in this sense is the silkworm.
