or·gan·elle

O0115600 (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.

Translations

Organelle

enUK

organelle

[¦ȯr·gə¦nel] (cell and molecular biology) A specialized subcellular structure, such as a mitochondrion, having a special function; a condensed system showing a high degree of internal order and definite limits of size and shape.

Organelle

 

a part of the body of a unicellular organism, or protozoan, that performs any one of various functions. Organelles are especially diverse and complex in Infusoria and Flagellata. There are several types of organelles. Skeletal and support organelles protect the organism from mechanical, chemical, and other harmful effects (for example, the shells of Sarcodina and Infusoria). There also are locomotor and contractile organelles (for example, flagella, cilia, and myonemes); sensory, or receptor, organelles (for example, photosensitive ocelli); and attack and defense organelles (for example, in Infusoria, the rod-shaped formations known as trichocysts, which are discharged from the body). Digestive organelles capture, conduct, and digest the food (for example, the digestive vacuoles of Infusoria). There are also excretory and secretory organelles (for example, the pulsating vacuoles of Infusoria). The term “organelle” is often used as a synonym for “organoid.”

organelle

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, apparatus" >Golgi apparatus, and reticulum" >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

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.
