The process in which a cell becomes capable of differentiating autonomously into a sensory organ precursor cell regardless of its environment; upon determination, the cell fate cannot be reversed.

A process that is carried out at the cellular level which results in dynamic structural changes to the arrangement of constituent parts of cytoskeletal structures comprising actin filaments and their associated proteins.

The establishment, maintenance and elaboration of the dorsal/ventral axis of the wing disc, a precursor to the adult wing.

A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.

The region that lies just beneath the plasma membrane on the apical edge of a cell.

Cytoplasm situated near, or occurring around, the nucleus.
