or·gan·elle

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

[New Latin organella, diminutive of Medieval Latin organum, organ of the body, from Latin, implement, tool; see organ.]

organelle

(ˌɔːɡəˈnɛl)
n
(Biology) a structural and functional unit, such as a mitochondrion, in a cell or unicellular organism
[C20: from New Latin organella, from Latin organum: see organ]

or•gan•elle

(ˌɔr gəˈnɛl, ˈɔr gəˌnɛl)

n.
a specialized cell structure that has a specific function; a cell organ.
[1905; < New Latin organella organ]

or·gan·elle

(ôr′gə-nĕl′)
A structure or part that is enclosed within its own membrane inside a cell and has a particular function. Organelles are found only in eukaryotic cells and are absent from the cells of prokaryotes like bacteria. The nucleus, mitochondrion, and chloroplast are examples of organelles.

organelle

A specialized structure inside a cell, e.g. a chloroplast.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.organelle - a specialized part of a cell; analogous to an organ; "the first organelle to be identified was the nucleus"
cell - (biology) the basic structural and functional unit of all organisms; they may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals
cilium - a hairlike projection from the surface of a cell; provides locomotion in free-swimming unicellular organisms
organ - a fully differentiated structural and functional unit in an animal that is specialized for some particular function
lysosome - an organelle found in the cytoplasm of most cells (especially in leukocytes and liver and kidney cells)
cell nucleus, karyon, nucleus - a part of the cell containing DNA and RNA and responsible for growth and reproduction
nucleole, nucleolus - a small round body of protein in a cell nucleus; such organelles contain RNA and are involved in protein synthesis
chondriosome, mitochondrion - an organelle containing enzymes responsible for producing energy
centriole - one of a pair of small cylindrical cell organelles near the nucleus in animal cells; composed of nine triplet microtubules and form the asters during mitosis
ribosome - an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell; "the ribosome is the site of protein synthesis"

This allows contemplation of questions regarding the next level of complexity: how these ribosomes work and evolve how the ribosomal components imported from cytosol are assembled with the organellar rrna into a functional unit being maturated in different compartments in organelles which trans-factors are involved in this process how the chlororibosomal activity is spatiotemporally coupled to the synthesis and incorporation of functionally essential pigments what are the specific regulatory mechanisms to address these questions, there is a need to first to characterize the process of translation in organelles on the structural level.
Morphofunctional abnormalities in AT, adipocyte hypertrophy and organellar dysfunction (especially mitochondrial dysfunction and endoplasmic reticulum (ER) stress), impaired angiogenesis and hypoxia, insufficient adipogenesis, imbalance between apoptosis and adipogenesis, disturbances in the remodeling or degradation of extracellular matrix (ECM), all could lead to activation of numerous immune mechanisms.
(6) Although molecular biological studies on the structure of organellar DNA and the sequencing of organelle genomes has progressed, (7) it has proved difficult to observe DNA in mitochondria and plastids in vivo (Fig.
Genetic studies suggest a mutation in the lysosomal trafficking regulator (CHS1/LYST) gene located at 1q42, resulting in abnormal organellar protein trafficking and aberrant fusion of vesicles, further resulting in a failure to transport lysosomes to the appropriate site of action.
If the genome has been fragmented and expanded based on recombination events in an analogous manner to plant organellar genomes, this may be a way of protecting against damage by having "extra" genetic material that can be modified by oxidative damage and/or recombination and subsequently edited back to the canonical sequence.
