Which statement about metamorphosis is true?

• A. It occurs without any change in form.
• B. It only occurs in adult insects.
• C. It describes the physical and physiological changes as an insect grows through immature stages to an adult.
• D. It is unrelated to growth.

Answer: (C)

Metamorphosis is the process of transformation insects undergo as they grow from immature stages to adults, involving major physical and physiological changes. Many insects pass through distinct stages—egg, larva, pupa, and adult—where the immature form can look very different from the adult and have different habits. Some groups develop more gradually, with nymphs resembling small adults but continuing to mature. This transformation is linked to growth and development, not to staying the same or being unrelated to growth. So the statement that metamorphosis describes the physical and physiological changes as an insect grows through immature stages to an adult is correct.
