The transformation of the larva into an adult through drastic changes is known as which of the following?

Correct option is D

The correct answer is (d) Metamorphosis

Metamorphosis refers to the biological process by which an organism undergoes significant physical and structural changes during its development from a larval (immature) stage to an adult. These changes involve reorganization of tissues, body structures, and physiological systems.

• Insects:
  • Caterpillar (larva) transforming into a butterfly (adult).
• Amphibians:
  • Tadpole transitioning into a frog.

1. Complete Metamorphosis (Holometabolous):

   • Stages: Egg → Larva → Pupa → Adult.
   • Example: Butterfly.

2. Incomplete Metamorphosis (Hemimetabolous):

   • Stages: Egg → Nymph → Adult.
   • Example: Grasshopper.

• Viviparous: Animals that give birth to live young (e.g., humans, most mammals).
• Oviparous: Animals that lay eggs (e.g., birds, reptiles, some fish).
• Embryo: The early developmental stage of an organism, typically before hatching or birth.
