|
cytoplasm
|
The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
|
GO:0005575
|
cellular_component
|
A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex). |
|
GO:0005622
|
intracellular anatomical structure
|
A component of a cell contained within (but not including) the plasma membrane. In eukaryotes it includes the nucleus and cytoplasm. |
|
GO:0110165
|
cellular anatomical structure
|
A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses. |
|
GO:0043227
|
membrane-bounded organelle
|
Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
|
GO:0043226
|
organelle
|
Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. |
|
GO:0043229
|
intracellular organelle
|
Organized structure of distinctive morphology and function, occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane. |
|
GO:0043231
|
intracellular membrane-bounded organelle
|
Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
|
GO:0016020
|
membrane
|
A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. |
|
GO:0098588
|
bounding membrane of organelle
|
The lipid bilayer that forms the outer-most layer of an organelle. |
|
GO:0031090
|
organelle membrane
|
A membrane that is one of the two lipid bilayers of an organelle envelope or the outermost membrane of single membrane bound organelle. |
|
GO:0005774
|
vacuolar membrane
|
The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell. |
|
GO:0005773
|
vacuole
|
A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol. |
|
GO:0000323
|
lytic vacuole
|
A vacuole that is maintained at an acidic pH and which contains degradative enzymes, including a wide variety of acid hydrolases. |
|
GO:0098852
|
lytic vacuole membrane
|
The lipid bilayer surrounding a lytic vacuole and separating its contents from the cytoplasm of the cell. |
|
GO:0005764
|
lysosome
|
A small lytic vacuole that has cell cycle-independent morphology found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions. |
|
GO:0005765
|
lysosomal membrane
|
The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm. |
