The chemical reactions and pathways resulting in the formation of chitin, a linear polysaccharide consisting of beta-(1->4)-linked N-acetyl-D-glucosamine residues.

The morphogenesis of an embryonic epithelium into a tube-shaped structure.

The chemical reactions and pathways resulting in the formation of cuticle chitin, a linear polysaccharide consisting of beta-(1->4)-linked N-acetyl-D-glucosamine residues, found in cuticles.

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.

The process in which the anatomical structures of the Malpighian tubule are generated and organized. This process takes place entirely during the embryonic phase. A Malpighian tubule is a fine, thin-walled excretory tubule in insects which leads into the posterior part of the gut.

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.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to the organism.

Ensuring that a tube in an open tracheal system is of the correct diameter. When primary branches form their lumens are small (less than 2 micrometers) in caliber and must undergo regulated expansion during larval life to reach their mature size.

Ensuring that a tube in an open tracheal system is of the correct length.

The process in which a trachea is generated and organized. The trachea is the portion of the airway that attaches to the bronchi as it branches.

The chemical reactions and pathways resulting in the formation of cell wall chitin, a linear polysaccharide consisting of beta-(1->4)-linked N-acetyl-D-glucosamine residues, found in the walls of cells.

Construction of the eggshell, a product of the somatic follicle cell epithelium and a structure that supports the egg in a hostile environment, minimizing water loss whilst allowing gas exchanges essential for embryonic respiration.

Any process that activates or increases the frequency, rate or extent of protein localization to cell cortex.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

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.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.
