Question

The female silk moth lays 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 protein. Q6-Which stage of life cycle of silk moth is directly related in formation of silk fibre *
a)female silk moth
b)caterpillar
c)pupa
d) both b and c​

Answer 1

Answer:

c) Pupa.

Explanation:

In the Pupa stage, a weave is netted around by the silkworm to hold itself. After that it swings its head, spinning a fibre made of a protein and it becomes a silk fibre.

The Pupa stage is also known as the stage in which the fully-grown silkworm attaches itself to a twig and weaves a cover around itself. In this stage the silkworm shows no movement or motion.
