FAQs on Steps in Sericulture: From Cocoon to Silk Video Lecture - Advance Learner Course: Science Class 6

1. What is sericulture?

Ans. Sericulture refers to the process of cultivating silk from silkworms. It involves various stages, including rearing silkworms, harvesting cocoons, and extracting silk fibers.

2. How long does it take for a silkworm to spin a cocoon?

Ans. It takes approximately two to three days for a silkworm to spin a cocoon. During this time, the silkworm secretes a liquid silk substance that hardens upon contact with the air and forms a protective cocoon.

3. What happens inside a silkworm cocoon?

Ans. Inside a silkworm cocoon, the silkworm undergoes metamorphosis. It transforms from a larva into a pupa and later into a moth. The cocoon provides a safe environment for this transformation to occur.

4. How is silk extracted from the cocoon?

Ans. Silk extraction involves a process called reeling. The cocoons are soaked in hot water to soften the sericin, a natural gum-like substance that holds the cocoon together. The softened cocoon is then unwound, and the silk fibers are carefully collected and spun together to form silk threads.

5. What are the uses of silk?

Ans. Silk has numerous uses, including the production of clothing, textiles, and accessories. It is highly valued for its softness, durability, and luxurious texture. Silk is also used in the manufacturing of home furnishings, such as curtains and bedding, due to its lustrous appearance and natural insulation properties.
