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. |

|
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. |

|
localization
|
Any process in which a cell, a substance, or a cellular entity, such as a protein complex or organelle, is transported, tethered to or otherwise maintained in a specific location. In the case of substances, localization may also be achieved via selective degradation. |
|
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:0016043

|
A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component. |
|
GO:0051234
|
establishment of localization
|
Any process that localizes a substance or cellular component. This may occur via movement, tethering or selective degradation. |
|
GO:0006810
|
transport
|
The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or a transporter complex, a pore or a motor protein. |
|
GO:0050896
|
response to stimulus
|
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism. |
|
GO:0051649
|
establishment of localization in cell
|
Any process, occurring in a cell, that localizes a substance or cellular component. This may occur via movement, tethering or selective degradation. |
|
GO:0051641
|
cellular localization
|
A cellular localization process whereby a substance or cellular entity, such as a protein complex or organelle, is transported to, and/or maintained in, a specific location within a cell including the localization of substances or cellular entities to the cell membrane. |
|
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:0016192
|
vesicle-mediated transport
|
A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane. |
|
GO:0032501
|
multicellular organismal process
|
Any biological process, occurring at the level of a multicellular organism, pertinent to its function. |
|
GO:0090174
|
organelle membrane fusion
|
The joining of two lipid bilayers to form a single organelle membrane. |
|
GO:0048284
|
organelle fusion
|
The creation of a single organelle from two or more organelles. |
|
GO:0061025
|
membrane fusion
|
The membrane organization process that joins two lipid bilayers to form a single membrane. |
|
GO:0016050
|
vesicle organization
|
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a vesicle. |
|
GO:0046903
|
secretion
|
The controlled release of a substance by a cell or a tissue. |
|
GO:0046649
|
lymphocyte activation
|
A change in morphology and behavior of a lymphocyte resulting from exposure to a specific antigen, mitogen, cytokine, chemokine, cellular ligand, or soluble factor. |
|
GO:0045321
|
leukocyte activation
|
A change in morphology and behavior of a leukocyte resulting from exposure to a specific antigen, mitogen, cytokine, cellular ligand, or soluble factor. |
|
GO:0001775
|
cell activation
|
A multicellular organismal process by which exposure to an activating factor such as a cellular or soluble ligand results in a change in the morphology or behavior of a cell. |
|
GO:0002376
|

|
GO:0042110
