What is metamorphosis? Give examples.

Metamorphosis is a biological process by which animals, including insects, amphibians and few aquatic animals undergo extreme and rapid physical changes someday after the birth. The effect of metamorphosis modifies the entire body of an organism. These variations include the maturation of enzymes, blood cells, the remodelling of the nervous systems, digestive systems.

Definition

It is defined as the process in which an animal’s body structure abruptly changes through cell growth and differentiation.

Example

Listed below are the example of metamorphosis. The life cycle of frogs and insects involve sequential stages of change.

Life cycle of insect

  • An adult silk moth starts its life from an egg. Eventually, it becomes a silkworm and later becomes a cocoon. At the last stage, a moth develops from the cocoon.

Life cycle of frog

If we consider the life cycle of a frog, there are three stages.

  • Eggs of a frog develop into a larva (tadpole) and later become an adult frog.
  • These drastic changes in appearance and stages are not as long as human growth.
  • The changes in the stages from a larva to an adult are known as metamorphism.
