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 zygospores are formed. Zygospores are characteristic of the zygomycete fungi (phylum Zygomycota) thick-walled and darkly colored, and usually heavily ornamented as well, with many spines or ridges. It is formed between two specialized organs called suspensors, which are themselves usually heavily ornamented, one from each mating partner. The zygospore forms between them and then breaks away. The process by which spores form outside a specialized end cell known as a basidium. Basidia are characteristic of the basidiomycete fungi (phylum Basidiomycota), and give rise to spores that each contain a haploid nucleus that is the product of meiosis. The spores are usually attached to the basidium by short spikes called sterigmata (singular: sterigma). In most basidiomycetes there are four sterigmata (and four spores) to a basidium. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. The formation of spores derived from the products of meiosis. The process whose specific outcome is the progression of a spore over time, from its initiation to the mature structure. A spore is a structure that can be used for dissemination, for survival of adverse conditions because of its heat and dessication resistance, and/or for reproduction. The process by which a relatively unspecialized cell acquires the specialized features of a cellular spore, 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. 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 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. The regular alternation, in the life cycle of haplontic, diplontic and diplohaplontic organisms, of meiosis and fertilization which provides for the production offspring. In diplontic organisms there is a life cycle in which the products of meiosis behave directly as gametes, fusing to form a zygote from which the diploid, or sexually reproductive polyploid, adult organism will develop. In diplohaplontic organisms a haploid phase (gametophyte) exists in the life cycle between meiosis and fertilization (e.g. higher plants, many algae and Fungi); the products of meiosis are spores that develop as haploid individuals from which haploid gametes develop to form a diploid zygote; diplohaplontic organisms show an alternation of haploid and diploid generations. In haplontic organisms meiosis occurs in the zygote, giving rise to four haploid cells (e.g. many algae and protozoa), only the zygote is diploid and this may form a resistant spore, tiding organisms over hard times. A developmental process by which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring. 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 male and female gametangia develop and fuse to form an oospore, a thick-walled resting spore of oomycetes. Any process that modulates the frequency, rate or extent of the formation of cellular spores derived from the products of meiosis. Any process that activates, maintains or increases the frequency, rate or extent of the formation of cellular spores derived from the products of meiosis. Any process that stops, prevents or reduces the frequency, rate or extent of the formation of cellular spores derived from the products of meiosis.
