The process whereby the R8 photoreceptor commits to its cell fate. The R8 receptor contributes the central part of the rhabdomere in the basal parts of the ommatidium. The process whereby a relatively unspecialized cell acquires the specialized features of a photoreceptor cell, as found in the eye, the primary visual organ of most organisms. The process whereby the R1/R6 photoreceptors commit to their cell fate. R1 and R6 are paired photoreceptors which contribute the outer rhabdomeres. The process whereby the developmental fate of a cell becomes restricted such that it will develop into a compound eye photoreceptor cell. A photoreceptor cell is a cell that responds to incident electromagnetic radiation. Different classes of photoreceptor have different spectral sensitivities and express different photosensitive pigments. The process whereby a relatively unspecialized cell acquires the specialized features of an eye photoreceptor cell. 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 whereby the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres. The process whereby the R2/R5 photoreceptors commit to their cell fate. R2 and R5 are paired photoreceptors which contribute the outer rhabdomeres. The process whereby the developmental fate of a cell becomes restricted such that it will develop into a photoreceptor cell. A photoreceptor cell is a cell that responds to incident electromagnetic radiation. Different classes of photoreceptor have different spectral sensitivities and express different photosensitive pigments. The process whereby the developmental fate of a cell becomes restricted such that it will develop into an eye photoreceptor cell. A photoreceptor cell is a cell that responds to incident electromagnetic radiation. Different classes of photoreceptor have different spectral sensitivities and express different photosensitive pigments. The process whereby the R7 photoreceptor commits to its cell fate. The R7 receptor contributes the central part of the rhabdomere in the apical parts of the ommatidium.
