Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates. The process by which the anatomical structures of the compound eye are generated and organized. Morphogenesis pertains to the creation of form. 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. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. The process by which the anatomical structures of the eye are generated and organized. Morphogenesis pertains to the creation of form. The formation and development of the equator that forms the boundary between the photoreceptors in the dorsal sector of the eye and those in the ventral sector, dividing the eye into dorsal and ventral halves. The process by which the anatomical structures of a polarized epithelium are generated and organized. Morphogenesis pertains to the creation of form. A polarized epithelium is an epithelium where the epithelial sheet is oriented with respect to the planar axis. The process by 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 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. Coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates. The developmental process by which the size or shape of a cell is generated and organized. Morphogenesis pertains to the creation of form. The process whose specific outcome is the progression of the compound eye over time, from its formation to the mature structure. Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns. The process whereby the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres.
