organelle

 [or″gah-nel´]
any of the organized cytoplasmic structures of distinctive morphology and function present in all eukaryotic cells, including such structures as the nucleus, mitochondria, lysosomes, peroxisomes, Golgi apparatus, and endoplasmic reticulum, as well as chloroplasts in plants and cilia and flagella in protozoa.

or·gan·elle

(or'găn-el),
One of the specialized parts of a protozoan or tissue cell; these subcellular units include mitochondria, the Golgi apparatus, nucleus and centrioles, granular and agranular endoplasmic reticulum, vacuoles, microsomes, lysosomes, plasma membrane, and certain fibrils, as well as plastids of plant cells.
Synonym(s): cell organelle, organoid (3)
[G. organon, organ, + Fr. -elle, dim. suffix, fr. L. -ella]

organelle

(ôr′gə-nĕl′)
n.
A differentiated structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function.

or·gan·elle

One of the specialized parts of a protozoan or tissue cell; mitochondria, the Golgi apparatus, nucleus and centrioles, granular and agranular endoplasmic reticulum, vacuoles, microsomes, lysosomes, plasma membrane, and certain fibrils, as well as plastids of plant cells.
Synonym(s): organoid (3) .

organelle

Any one of the bodies forming the internal functional components, or ‘little organs’, of the cell. The organelles include MITOCHONDRIA, the GOLGI APPARATUS, the ENDOPLASMIC RETICULUM, RIBOSOMES, LYSOSOMES and the CENTRIOLES.

organelle

any part of a cell that has a particular structural or functional role, such as FLAGELLUM or a MITOCHONDRION. Organelles are analogous with organs in the body of multicellular organisms.

Organelle

Specialized structure within a cell, which is separated from the rest of the cell by a membrane composed of lipids and proteins, where chemical and metabolic functions take place.

However, we challenged to isolate the very small organellar division machineries that are directly responsible for organelle division.
Immunoblotting revealed that the PRIP-type AQP was constitutively expressed during oogenesis in specific organellar membranes.
This shows that the supposed molecular, organellar, and cellular levels of the biohierarchy are in fact all on one level of magnitude, so are not three hierarchical levels in a series.
If the ITS and matK trees represent the nuclear and chloroplast phylogenies of Aesculus, respectively, the discordance between the two trees may imply that organellar lineage sorting (extinction of organellar lineages following speciation from a polymorphic ancestor) has occurred in Aesculus [ILLUSTRATION FOR FIGURE 4 OMITTED].
- DNA can be classified in two broad categories: nuclear and organellar. Nuclear genomes are much larger than organellar, ranging from [less than][10.sup.6] nucleotide bases (= 1000 kb [kilobase]) in some bacteria to [greater than][10.sup.11] in some plants (Cavalier-Smith 1985, Li et al.
Nipponbare, MSU release 7.0, GenBank accession PRJDB1747) and the organellar genomes (chloroplast genome, GenBank accession NC_001320.1; mitochondria genome, GenBank accession BA00029.3) using the alignment software BWA (version 0.6.2) with default parameters.
The functionality of mitochondrial metabolism is highly dependent on the maintenance of the organellar NAD pool.
The first such enzyme isolated from the vacuole is ZEN1, an S1-type [Zn.sup.2+]-dependent nuclease that plays a major role in nuclear DNA degradation, hydrolyzing nuclear and organellar DNA after vacuole collapse.
In the extreme view, a parasite represents the equivalent of an organellar genome, tracking hosts with such fidelity that incongruent genetic structure between host and parasite is assumed to reflect stochastic genealogical processes or different evolutionary rates rather than the possibility of semi-independent species histories (e.g.
2002), and previous genetic work revealed limited organellar genetic structuring range-wide (Baker et al.
