Question

The eggs of silkworm are stored in:
A. Gold box
B. Stripes of cloth
C. Plastic box
D. Iron box

Answer 1

Hint: In Silkworms eggs are being laid on the leaves of Mulberry trees. The eggs are covered with the gelatinous secretion by which this sticks to the leaves. Eggs are further developed and undergo cycle.

Complete step by step solution: Female silkworm lays around 300 eggs. The female mouth that is silk warms these eggs and dies after laying eggs as adult silkworms have such small mouths that they cannot eat anything. The eggs are kept in a cool place so that they can be stored for a long time. Eggs of slikworm can be stored on stripes of cloth or paper. Mulberry leaves are the staple diet of silkworms. When the mulberry tree bears a fresh crop of leaves, the eggs are warmed suitably so that the larvae hatch from them. The larvae, caterpillars or silkworms are then stored in clean bamboo trays and are fed freshly chopped mulberry leaves. So from this it is clear that the larvae of silkworms are stored in stripes of clothes. Under favourable conditions eggs hatch into larvae in two weeks approximately.

So, the correct answer is option B.

Additional information: eggs of silkworms can remain viable in the refrigerator for 5 years. Direct sunlight in the morning for a few hours only hastens the hatching. So, once we take eggs out of the refrigerator, they can hatch in 5-7 days. Upon hatching silkworm larvae are just 2-3 mm in length and are very delicate.

Note: Silk is a natural fibre which comes from the cocoons of silkworms, which are the larvae of the mulberry silk moth Bombyx mori. This silk is manufactured in the factories for adding colours .
