 Tissue remodelling during morphogenesis is usually triggered by
 biological mechanisms, but it can be strongly affected by mechanical
 properties of the developing tissue and its surroundings. Understanding
 tissue mechanics is important part of morphogenesis description. During
 pupal stage of fruit fly (\textit{Drosophila melanogaster})
 development, wings are formed from imaginal discs. We have observed
 wild type, perturbed and \textit{dumpy} mutant wings from 16 to 32
 hours after pupa formation. Specialized software for cell tracking
 enables us to quantify contributions to tissue deformation from
 different cellular processes. We developed a hydrodynamic theory which
 accounts for observed tissue properties. Important contributions
 arising from active cell behavior differentiate living tissues from
 'passive'  non-living materials.
