The process whereby cells that are products of meiosis acquire the specialized features of ascospores. Ascospores are generally found in clusters of four or eight spores within a single mother cell, the ascus, and are characteristic of the ascomycete fungi (phylum Ascomycota). The process by which the nascent membrane forms at the meiotic outer plaque and grows until closure occurs and forespores, or prospores, are formed. A process, occurring at the cellular level, that is involved in the reproductive function of a single-celled organism. The aggregation, arrangement and bonding together of a cellular component. Structural modification of the spindle pole body that takes place during the second meiotic division during ascospore formation; includes the recruitment of sporulation-specific proteins to the outer plaque to form the meiotic outer plaque (MOP). The process by which a cellular component is synthesized, aggregates, and bonds together. Includes biosynthesis of constituent macromolecules, and those macromolecular modifications that are involved in synthesis or assembly of the cellular component. During ascospore formation, the process by which each haploid nucleus becomes encapsulated by a double membrane. The process whose specific outcome is the progression of the cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a specific fate. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a cellular component. The formation of spores derived from the products of meiosis. A cellular spore is a cell form that can be used for dissemination, for survival of adverse conditions because of its heat and dessication resistance, and/or for reproduction.
