GO:0007049 cell cycle The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
GO:0051321 meiotic cell cycle Progression through the phases of the meiotic cell cycle, in which canonically a cell replicates to produce four offspring with half the chromosomal content of the progenitor cell via two nuclear divisions.
GO:0016043 cellular component organization A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component.
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:0007126 meiotic nuclear division One of the two nuclear divisions that occur as part of the meiotic cell cycle.
GO:0006996 organelle organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an organelle within a cell. An organelle is an organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane.
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:0071840 cellular component organization or biogenesis A process that results in the biosynthesis of constituent macromolecules, assembly, arrangement of constituent parts, or disassembly of a cellular component.
GO:1902589 single-organism organelle organization An organelle organization which 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:0022402 cell cycle process The cellular process that ensures successive accurate and complete genome replication and chromosome segregation.
GO:0048285 organelle fission The creation of two or more organelles by division of one organelle.
GO:0000280 nuclear division The division of a cell nucleus into two nuclei, with DNA and other nuclear contents distributed between the daughter nuclei.
GO:0044848 biological phase A distinct period or stage in a biological process or cycle.
GO:0022403 cell cycle phase One of the distinct periods or stages into which the cell cycle is divided. Each phase is characterized by the occurrence of specific biochemical and morphological events.
GO:0051326 telophase The cell cycle phase which follows anaphase during M phase of mitosis and meiosis and during which the chromosomes arrive at the poles of the cell and the division of the cytoplasm starts.
GO:1903046 meiotic cell cycle process A process that is part of the meiotic cell cycle.
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:0098764 meiosis I cell cycle phase A meiotic cell cycle phase prior to a during which some part of meiosis I nuclear division or the proceeding cytokinesis occurs.
GO:0098762 meiotic cell cycle phase One of the distinct periods or stages into which the meiotic cell cycle is divided. Each phase is characterized by the occurrence of specific biochemical and morphological events.
GO:0007127 meiosis I The first meiotic nuclear division in which homologous chromosomes are paired and segregated from each other, producing two haploid daughter nuclei.
GO:0000705 achiasmate meiosis I The first division of meiosis in which homologous chromosomes are paired and segregated from each other, occurring in the constitutive absence of chiasmata.
GO:0007134 meiotic telophase I The cell cycle phase which follows anaphase I of meiosis and during which the chromosomes arrive at the poles of the cell and the division of the cytoplasm starts.
