Question

Which part of silkworms secretes silk?

Answer 1

Answer:

Silk is secreted from the two salivary glands in the head of the silkworm.

Answer 2

Answer:

saliva

Explanation:

The silk is a continuous filament comprising fibroin protein, secreted from two salivary glands in the head of each worm, and a gum called sericin, which cements the filaments. The sericin is removed by placing the cocoons in hot water, which frees the silk filaments and readies them for reeling.
