Which cellular mechanism ensures that adult specific structures develop properly from imaginal discs during metamorphosis?

💡 Explanation

During metamorphosis controlled apoptosis carves specific adult structures from imaginal discs shaping wings legs and antennae; this process precisely eliminates larval cells via intrinsic death pathways modulated by hormonal cues. Therefore programmed cell death results by apoptosis, rather than nuclear translocation or increased chromosomal crossover requires entirely different signals.
