Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates. Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns. The developmental process pertaining to the initial formation of an anatomical structure from unspecified parts. This process begins with the specific processes that contribute to the appearance of the discrete structure and ends when the structural rudiment is recognizable. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. 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. The process by which the limits of an anatomical structure are generated. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. 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 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.
