A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of chromosomes, structures composed of a very long molecule of DNA and associated proteins that carries hereditary information. A change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a steroid hormone stimulus. The decondensing (loosening) and swelling of the chromosomal sites of target genes on polytene chromosomes following response to a stimulus, to facilitate sudden bursts of transcriptional activity in response to transient environmental signals. A change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a ecdysone stimulus. The decondensing (loosening) and swelling of the chromosomal sites of hormone-responsive genes on polytene chromosomes in response to increased production of the steroid hormone 20-hydroxyecdysone (ecdysone) in Drosophila larvae approaching pupation. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a ecdysone stimulus.
