General Information
Term photoreceptor cell fate commitment ID (Ontology) GO:0046552 (Gene Ontology)
Definition The process in which 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.
