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"

During the process, nutrients are recycled by the lysosome, an internal organelle, to produce metabolites that can be used by the cell.
Organelle purification from plant cells is more challenging than from animal cells due to cell walls, vacuoles and relatively low organelle concentrations and each plant tissue is different.
The genes governing production of mitochondria, both in the nucleus and in the organelle itself, can be defective, and the defects can be passed from mothers to their children.
Many important biological functions require precisely arranged groups of different enzymes working in concert, often inside a cellular subcomponent called an organelle.
These results suggest that AX protects the cell organelle mitochondria and nucleus of the nematode, resulting in a life span extension via an Ins/IGF-1 signaling pathway during normal aging, at least in part.
If this is a correct reading of the fossil record, it implies that no new kinds of organelle, and no wholly new kinds of algae, have been permitted to arise by symbiosis during the last 540 million years or so.
Organelle degradation is triggered in the center of the lens during embryonic development and is characterized by the rapid and coordinated disappearance of all membrane-bound organelles [16].
