.... The Drosophila larva consists predominantly of differentiated polyploid tissues that support the growth and eventual metamorphosis of the mitotic imaginal discs and nervous system, which will give rise to the tissues of the adult animal (see Gilbert, 2003 ). Although growth of the imaginal discs...
