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.organelleA specialized structure inside a cell, e.g. a chloroplast.ThesaurusNoun | 1. | organelle - a specialized part of a cell; analogous to an organ; "the first organelle to be identified was the nucleus"cell organ, cell organellecell - (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 animalscilium - a hairlike projection from the surface of a cell; provides locomotion in free-swimming unicellular organismsorgan - a fully differentiated structural and functional unit in an animal that is specialized for some particular functionlysosome - 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 reproductionnucleole, nucleolus - a small round body of protein in a cell nucleus; such organelles contain RNA and are involved in protein synthesischondriosome, mitochondrion - an organelle containing enzymes responsible for producing energycentriole - 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 mitosisribosome - 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" | Translations
OrganelleenUK
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.” organelleenUK
