Which developmental problem arises if imaginal discs fail to receive ecdysone signal during metamorphosis?

💡 Explanation

When imaginal discs don't receive ecdysone, cell differentiation into adult structures does not occur because ecdysone triggers the genetic cascade for metamorphosis. Therefore, the absence of adult structures results, rather than premature differentiation, exoskeleton changes, or lipid disruption, which involve distinct hormonal pathways.
