Silk fibre is obtained from the stem of a plant.

A) True

B) False

Natural fibres are fibres obtained from plants and animals.

• Plant-based fibres: These come from plants. Examples include coconut, hemp, and jute.
• Animal-based fibres: These are derived from animals. Examples include wool and silk.

Silk is a natural protein fibre composed of fibroin. It is produced by insect larvae to form cocoons. The most common source of silk is the silkworm (Bombyx mori), which feeds on mulberry leaves. Silk production occurs during the silkworm’s life cycle. Historically, silk was first produced in China and is widely used to make silk garments.

Silk can also be obtained from larvae of other insects, such as spiders and silverfish.
