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: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:0009555 pollen development The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. The pollen grain is surrounded by an elaborate cell wall. In some species, the generative cell immediately divides again to give a pair of sperm cells. In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates.
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: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: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:0055046 microgametogenesis The process whose specific outcome is the progression of the pollen grain over time, from its formation as the microspore to the mature structure.
