STUDY OF SILK FIBER OFFSPRING IN BIOLOGY CLASSES

Abstract

The silk separation gland consists of tubes divided into three pieces, located on either side of the worm’s body. Silk - occurs in the silk secretory glands of the silkworm. The size of the silk gland is 40% of the total size of the worm, the length of which is 5 times the length of the worm's body when stretched. As the fibroin formed in the lower pair of silk-separating glands passes through the reservoir, it is surrounded by sericin and emerges in the form of two streams that do not coalesce along the single excretory tract. Accordingly, the cocoon strip consists of two fibers coated with sericin and glued. The cross section of the cocoon is reminiscent of an ellipse divided into two equal pieces.
