The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field. The process whereby the developmental fate of a cell becomes restricted such that it will develop into a stomatal guard cell. Guard cells are located in the leaf epidermis and pairwise surround stomatal pores, which allow CO2 influx for photosynthetic carbon fixation and water loss via transpiration to the atmosphere. A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition. The process by which the anatomical structures of the stomatal complex are generated and organized. Morphogenesis pertains to the creation of form. The stomatal complex is the stomatal guard cells and their associated epidermal cells. The process whereby a guard mother cell acquires the specialized features of a guard cell. The process whereby relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. The process whereby a relatively unspecialized cell acquires specialized features of an epidermal cell, any of the cells making up the epidermis.
