Which metamorphosis type involves no drastic change from juvenile to adult?

1. Simple

2. Gradual

3. Complete

4. Transitional

The correct answer is: Simple

The metamorphosis type that involves no drastic change from juvenile to adult is simple metamorphosis. In this type of metamorphosis, the young organisms, often referred to as nymphs, closely resemble the adults and typically undergo only minor changes as they grow. This contrasts with other types of metamorphosis where more significant transformation occurs. For example, in gradual metamorphosis, while there are still developmental stages separating the juvenile from the adult, the changes are gradual and less pronounced than in complete metamorphosis, where organisms undergo distinct stages like larva and pupa before becoming adults. Transitional metamorphosis may suggest some form of significant change as well. In simple metamorphosis, however, the continuity between juvenile and adult forms is much more apparent, making it a straightforward transition in development. This characteristic highlights why simple metamorphosis is the correct answer.
