|
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: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:0008150
|
biological_process
|
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. |

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:0016043
|
cellular component organization
|
A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component. |
|
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:0048285
|
organelle fission
|
The creation of two or more organelles by division of one organelle. |
|
GO:0022402
|
cell cycle process
|
The cellular process that ensures successive accurate and complete genome replication and chromosome segregation. |
|
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: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: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:1903046
|
meiotic cell cycle process
|
A process that is part of the meiotic cell cycle. |
|
GO:0019953
|
sexual reproduction
|
A type of reproduction that combines the genetic material of two gametes (such as a sperm or egg cell or fungal spores). The gametes have an haploid genome (with a single set of chromosomes, the product of a meiotic division) and combines with one another to produce a zygote (diploid). |
|
GO:0061640
|
cytoskeleton-dependent cytokinesis
|
A cytokinesis that involves the function of a set of proteins that are part of the microfilament or microtubule cytoskeleton. |
|
GO:0051301
|
cell division
|
The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells. |
|
GO:0061024
|
membrane organization
|
A process which results in the assembly, arrangement of constituent parts, or disassembly of a membrane. A membrane is a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. |
|
GO:0000910
|
cytokinesis
|
The division of the cytoplasm and the plasma membrane of a cell and its partitioning into two daughter cells. |
|
GO:0090148
|
membrane fission
|
A process that is carried out at the cellular level which results in the separation of a single continuous membrane into two membranes. |
|
GO:0140013
|
meiotic nuclear division
|
One of the two nuclear divisions that occur as part of the meiotic cell cycle. |
|
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:0007143
|
female meiotic nuclear division
|
A cell cycle process by which the cell nucleus divides as part of a meiotic cell cycle in the female germline. |
|
GO:0033206
|
meiotic cytokinesis
|
A cell cycle process that results in the division of the cytoplasm of a cell after meiosis, resulting in the separation of the original cell into two daughter cells. |
|
GO:0040038
|
polar body extrusion after meiotic divisions
|
The cell cycle process in which two small cells are generated, as byproducts destined to degenerate, as a result of the first and second meiotic divisions of a primary oocyte during its development to a mature ovum. One polar body is formed in the first division of meiosis and the other in the second division; at each division, the cytoplasm divides unequally, so that the polar body is of much smaller size than the developing oocyte. At the second division in which a polar body is formed, the polar body and the developing oocyte each contain a haploid set of chromosomes. |
