Fusion of the membrane of a transport vesicle with its target membrane.

The regulated release of neurotransmitter from the presynapse into the synaptic cleft via calcium regualated exocytosis during synaptic transmission.

Construction of a stage-1 egg chamber in the anterior part of the germarium, from the progeny of germ-line and somatic stem cells. An example of this is found in Drosophila melanogaster.

Formation of terminal branches in the open tracheal system. These are long cytoplasmic extensions that form fine tubules that transport oxygen directly to the tissues. An example of the process is found in Drosophila melanogaster.

Any process that stops, prevents or reduces the rate or extent of cell proliferation.

The initial (indirect) attachment of a synaptic vesicle membrane to the presynaptic active zone membrane, mediated by proteins protruding from the membrane and proteins of the presynaptic active zone cytoplasmic component. Synaptic vesicle tethering is the first step in this process.

A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.

The homotypic fusion of endocytic vesicles to form or add to an early endosome.

The onset of prepupal development when the larval stops crawling, everts its spiracles and the larval cuticle becomes the puparium or pupal case that surrounds the organism for the duration of metamorphosis.

Any cellular process that results in the specification, formation or maintenance polarization of a cell's architecture along its apical/basal axis so that the apical and basal regions of the cell have different membrane, extracellular matrix and sub-membrane cellular components.

The increase in size or mass of an entire multicellular organism, as opposed to cell growth.

Any process that activates or increases the frequency, rate or extent of endocytosis.

Transport of a vesicle from the plasma membrane to the endosome.

The process whose specific outcome is the progression of an epithelium over time, from its formation to the mature structure. An epithelium is a tissue that covers the internal or external surfaces of an anatomical structure.

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.

A membrane-bounded organelle that receives incoming material from primary endocytic vesicles that have been generated by clathrin-dependent and clathrin-independent endocytosis; vesicles fuse with the early endosome to deliver cargo for sorting into recycling or degradation pathways.

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

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

A protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers. One well-characterized example is the neuronal SNARE complex formed of synaptobrevin 2, syntaxin 1a, and SNAP-25.
