- The rearing of silkworms for obtaining silk is called sericulture. The female silk moth lays hundreds of eggs, from which hatch larvae which are called caterpillars or silkworms.
- They grow in size and when the caterpillar is ready to enter the next stage of its life history called pupa, it first weaves a net to hold itself.
- Then it swings its head from side to side in the form of the figure of eight (8). During these movements of the head, the caterpillar secretes fibre made of a protein which hardens on exposure to air and becomes silk fibre.

Consider the following assertions in terms of silk1. The rearing of s...
Silk is a natural fiber that is obtained from the cocoons of silkworms. It has been used for thousands of years to make luxurious fabrics. Let's analyze the given assertions about silk:
1. The rearing of silkworms for obtaining silk is called sericulture.
- This assertion is correct. Sericulture is the term used to describe the process of raising silkworms for the production of silk. It involves the cultivation of mulberry trees, which are the primary food source for silkworms, and the careful management of silkworms through their various stages of development.
2. Silk fibers are made of proteins.
- This assertion is also correct. Silk fibers are primarily composed of proteins. The main protein present in silk is fibroin, which makes up about 70-80% of the fiber. Fibroin is a strong and flexible protein that gives silk its unique properties, such as its lustrous appearance and smooth texture.
Silk is produced by the silkworms during their pupal stage. The silkworm larvae spin a protective cocoon made of silk fibers to undergo metamorphosis into adult moths. These silk fibers are secreted from the salivary glands of the silkworm larvae and harden upon exposure to air. The process of obtaining silk involves carefully unraveling the cocoon to extract the long continuous silk fibers.
Silk has been highly valued throughout history for its luxurious feel and lustrous appearance. It is used in the production of various textiles and fabrics, including clothing, scarves, and home furnishings. The process of sericulture plays a crucial role in the production of silk, as it ensures the healthy growth and development of silkworms.
In conclusion, both assertions are correct. Sericulture refers to the rearing of silkworms for obtaining silk, and silk fibers are indeed made of proteins, primarily fibroin.
