Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates.

Orientation of hairs in the imaginal disc-derived wing along a proximal-distal axis, such that each cell of the wing produces one wing hair which points in a distal direction.

Orientation of hairs in the imaginal disc-derived wing along a proximal-distal axis, such that each cell of the wing produces one wing hair which points in a distal direction.

The morphogenetic process in which the anatomical structures of a polarized epithelium are generated and organized. A polarized epithelium is an epithelium where the epithelial sheet is oriented with respect to the planar axis.

The morphogenetic process in which the anatomical structures of the compound eye are generated and organized. The adult compound eye is a precise assembly of 700-800 ommatidia. Each ommatidium is composed of 20 cells, identified by cell type and position. An example of compound eye morphogenesis is found in Drosophila melanogaster.

The attachment of a plasma membrane adhesion molecule in one cell to an identical molecule in an adjacent cell.

A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).

The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

Division of the 14 parasegments of the embryo into anterior and posterior compartments; exemplified by the actions of the segment polarity gene products.

The process in which the anatomical structures of the salivary gland are generated and organized.

The process in which the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres.

The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.

The asymmetric division of cells to produce two daughter cells with different developmental potentials. It is of fundamental significance for the generation of cell diversity.

The process in which photoreceptors are arranged in ommatidia in the dorsal and ventral fields to be mirror images. The polarity is established in the imaginal discs concurrently with cell fate specification.

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.

The specification and formation of anisotropic intracellular organization or cell growth patterns.

Any process that modulates the frequency, rate or extent of the assembly of actin filament bundles.

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

Any process that modulates the frequency, rate or extent of hemocyte proliferation. Hemocytes are blood cells associated with a hemocoel (the cavity containing most of the major organs of the arthropod body) which are involved in defense and clotting of hemolymph, but not involved in transport of oxygen. An example of this is found in Drosophila melanogaster.

The process that gives rise to the patterns of cell differentiation in the chitin-based larval cuticle. An example of this is found in Drosophila melanogaster.

A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of an imaginal disc-derived wing hair. A wing hair is an actin-rich, polarized, non-sensory apical projection that protrudes from each of the approximately 30,000 wing epithelial cells. An example of this is found in Drosophila melanogaster.

Determination of the site in the cell of an imaginal disc-derived wing at which a prehair initiates outgrowth. Restriction of prehair initiation to the distalmost part of a cell is essential to ensure that each wing epithelial cell produces one adult hair that points distally.

The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part.

The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part.

The specification and formation of the apicobasal polarity of an epithelial cell.

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

Long distance growth of a single axon process involved in cellular development.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes. In this pathway, the activated receptor signals via downstream effectors that result in the inhibition of beta-catenin phosphorylation, thereby preventing degradation of beta-catenin. Stabilized beta-catenin can then accumulate and travel to the nucleus to trigger changes in transcription of target genes.

The series of molecular signals initiated by binding of a Wnt protein to a receptor on the surface of the target cell where activated receptors signal via downstream effectors including C-Jun N-terminal kinase (JNK) to modulate cytoskeletal elements and control cell polarity.

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

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

The component of the plasma 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.
