The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster. Process by which a cell becomes capable of differentiating autonomously into an epithelial cell within an open tracheal system regardless of its environment; upon determination, the cell fate cannot be reversed. Tracheal cells are set aside as 10 clusters of approximately 80 cells on each side of the embryo (termed tracheal placodes). An example of this is found in Drosophila melanogaster. The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field. The progression of the respiratory system over time from its formation to its mature structure. The respiratory system carries out respiratory gaseous exchange. Process involved in cell fate commitment. Once determination has taken place, a cell becomes committed to differentiate down a particular pathway regardless of its environment. A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition.
