Answer to Question #67206 in Zoology for Aliza Khan

Question

Why is the growth in insects restricted and how do they overcome this hindrance

Answer 1

Growth in insects is restricted by their exoskeleton made of chitin. They overcome this problem by molting. After the removal of old hard chitin layer, insects become covered with new soft chitin. While it is undergoing chemical changes, which result in its hardening, the insect has time to grow. Molting is regulated by special hormones.
