EOG8H48JJ GO:0045177 1/82 apical part of cell cellular_component "The region of a polarized cell that forms a tip or is distal to a base. For example, in a polarized epithelial cell, the apical region has an exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue." [GOC:mah, ISBN:0815316194] EOG8H48JJ GO:0008362 1/82 chitin-based embryonic cuticle biosynthetic process biological_process "Synthesis, including the chemical reactions and pathways resulting in the formation of chitin and other components, and deposition of a chitin-based embryonic cuticle by the underlying epidermal epithelium. This tough, waterproof cuticle layer is essential to provide structural integrity of the larval body. An example of this is found in Drosophila melanogaster." [GOC:bf, GOC:mtg_sensu, PMID:12019232] EOG8H48JJ GO:0007424 1/82 open tracheal system development biological_process "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." [GOC:mtg_sensu, PMID:8625828] EOG8H48JJ GO:0007475 1/82 apposition of dorsal and ventral imaginal disc-derived wing surfaces biological_process "The coming together of the dorsal and ventral surfaces of the imaginal disc-derived wing during the conversion of a folded single layered wing disc to a flat bilayered wing." [GOC:bf, GOC:mtg_sensu] EOG8H48JJ GO:0040005 1/82 chitin-based cuticle attachment to epithelium biological_process "Attaching of a chitin-containing cuticle to the epithelium underlying it. An example of this process is found in Drosophila melanogaster." [GOC:bf, GOC:mtg_sensu]
