GO:0007275 multicellular organismal development The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
GO:0019953 sexual reproduction A reproduction process that creates a new organism by combining the genetic material of two organisms. It occurs both in eukaryotes and prokaryotes: in multicellular eukaryotic organisms, an individual is created anew; in prokaryotes, the initial cell has additional or transformed genetic material. In a process called genetic recombination, genetic material (DNA) originating from two different individuals (parents) join up so that homologous sequences are aligned with each other, and this is followed by exchange of genetic information. After the new recombinant chromosome is formed, it is passed on to progeny.
GO:0032502 developmental process A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition.
GO:0030154 cell differentiation The process in which 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.
GO:0009987 cellular process Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
GO:0044763 single-organism cellular process Any process that is carried out at the cellular level, occurring within a single organism.
GO:0044699 single-organism process A biological process that involves only one organism.
GO:0008150 biological_process Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
GO:0000003 reproduction The production of new individuals that contain some portion of genetic material inherited from one or more parent organisms.
GO:0051704 multi-organism process A biological process which involves another organism of the same or different species.
GO:0022414 reproductive process A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
GO:0044702 single organism reproductive process A biological process that directly contributes to the process of producing new individuals, involving a single organism.
GO:0044703 multi-organism reproductive process A biological process that directly contributes to the process of producing new individuals, involving another organism.
GO:0044707 single-multicellular organism process A biological process occurring within a single, multicellular organism.
GO:0032501 multicellular organismal process Any biological process, occurring at the level of a multicellular organism, pertinent to its function.
GO:0044767 single-organism developmental process A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition, involving only one organism.
GO:0048856 anatomical structure development The biological process whose specific outcome is the progression of an anatomical structure from an initial condition to its mature state. This process begins with the formation of the structure and ends with the mature structure, whatever form that may be including its natural destruction. 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.
GO:0048869 cellular developmental process A biological process whose specific outcome is the progression of a cell over time from an initial condition to a later condition.
GO:0003006 developmental process involved in reproduction A developmental process in which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring.
GO:0032504 multicellular organism reproduction The biological process in which new individuals are produced by one or two multicellular organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
GO:0048609 multicellular organismal reproductive process The process, occurring above the cellular level, that is pertinent to the reproductive function of a multicellular organism. This includes the integrated processes at the level of tissues and organs.
GO:0007276 gamete generation The generation and maintenance of gametes in a multicellular organism. A gamete is a haploid reproductive cell.
GO:0007292 female gamete generation Generation of the female gamete; specialised haploid cells produced by meiosis and along with a male gamete takes part in sexual reproduction.
GO:0022412 cellular process involved in reproduction in multicellular organism A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular organism.
GO:0048229 gametophyte development The process whose specific outcome is the progression of the gametophyte over time, from its formation to the mature structure. The gametophyte is the gamete-producing individual or phase in the life cycle having alternation of generations. An example of this process is found in Arabidopsis thaliana.
GO:0009553 embryo sac development The process whose specific outcome is the progression of the embryo sac over time, from its formation to the mature structure. The process begins with the meiosis of the megasporocyte to form four haploid megaspores. Three of the megaspores disintegrate, and the fourth undergoes mitosis giving rise to a binucleate syncytial embryo sac. The two haploid nuclei migrate to the opposite poles of the embryo sac and then undergo two rounds of mitosis generating four haploid nuclei at each pole. One nucleus from each set of four migrates to the center of the cell. Cellularization occurs, resulting in an eight-nucleate seven-celled structure. This structure contains two synergid cells and an egg cell at the micropylar end, and three antipodal cells at the other end. A binucleate endosperm mother cell is formed at the center. The two polar nuclei fuse resulting in a mononucleate diploid endosperm mother cell. The three antipodal cells degenerate.
GO:0009561 megagametogenesis The process whose specific outcome is the progression of the embryo sac over time, from its formation as the megaspore to the mature structure. The process begins when three of the four haploid megaspores disintegrate, and the fourth undergoes mitosis giving rise to a binucleate syncytial embryo sac. The two haploid nuclei migrate to the opposite poles of the embryo sac and then undergo two rounds of mitosis generating four haploid nuclei at each pole. One nucleus from each set of four migrates to the center of the cell. Cellularization occurs, resulting in an eight-nucleate seven-celled structure. This structure contains two synergid cells and an egg cell at the micropylar end, and three antipodal cells at the other end. A binucleate endosperm mother cell is formed at the center.
GO:0009560 embryo sac egg cell differentiation The process in which an uncellularized embryo sac nucleus cellularizes and acquires the specialized features of an egg cell. An example of this process is found in Arabidopsis thaliana.
