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

/or·ga·nelle/ (or″gah-nel´) a specialized structure of a cell, such as a mitochondrion, Golgi complex, lysosome, endoplasmic reticulum, ribosome, centriole, chloroplast, cilium, or flagellum.

organelle

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

organelle

[ôrgənel′]
Etymology: Gk, organon, instrument
1 any one of various specialized macromolecular structures bound within most cells, such as the mitochondria, the Golgi apparatus, the endoplastic reticulum, the lysosomes, and the centrioles.
2 any one of the tiny structures of protozoa associated with locomotion, metabolism, and other processes. Also called organella.

or·gan·elle

(ōr'gă-nel')
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) .
[G. organon, organ, + Fr. -elle, dim. suffix, fr. L. -ella]

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.
