Hormones in Other Organisms

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure through cell growth and differentiation.

Question :

Which hormone initiates the metamorphosis in frog ?

Solution :

Amphibian metamorphosis is the developmental process initiated by thyroid hormone which transforms a tadpole into a frog.



In several insect orders, the adult looks entirely different from the larva that preceded it. This marked transformation is called metamorphosis.

Metamorphosis takes place during a dormant stage called the pupa. The sequence of development extends as larval, pupal, and adult stages during normal development of the domestic silkworm moth. Hormone involved in the metamorphosis of silkworm moth is Prothoracicotropic Hormone (PTTH).
