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]

(ˌɔr gəˈnɛl, ˈɔr gəˌnɛl)

n.
a specialized cell structure that has a specific function; a cell 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"

Dentro de los eritrocitos, el evento inicial es la endocitosis de la hemoglobina, que es transportada hacia una organela denominada la vacuola digestiva acida (pH 5.2), donde los parasitos procesan entre un 60 y 80% de la hemoglobina presente en el globulo rojo.
Como se ha discutido a lo largo de la revision, el correcto funcionamiento del corazon, depende en esencia, de un correcto funcionamiento mitocondrial; y por tanto, mutaciones o disfunciones en esta organela, desencadena en cardiopatias.
Essa especificidade e direcionamento das moleculas quimicas sobre uma organela ou a inibicao dos processos vitais da celula pode acelerar o desenvolvimento de resistencia dos microrganismos aos antibioticos, pelo desenvolvimento de mutantes, novas cepas, ou pela criacao de mecanismos capazes de reconhecer a molecula malefica e ate transporta-la para o meio extracelular (Kretschmer et al., 2009).
El acrosoma es una organela membranosa de doble capa ubicada en la parte apical de la cabeza espermatica, que contiene distintas enzimas hidroliticas, como la hialuronidasa y la acrosina.
Sabe-se que o excesso de nutrientes sobrecarrega a mitocondria, levando ao aumento da producao de especies reativas de oxigenio que causam dano a esta organela celular.
La mitocondria es una organela esencial para todas las celulas eucariotas cuya funcion principal es la generacion de energia (1-3).
Este ultimo grupo de sustancias toxicas provoca la inhibicion de la respiracion mitocondrial y la sintesis de ATP por lo cual tambien se ve afectado el sistema carrier ADP/ATP a traves de la membrana de la organela mediante un bloqueo de la traslocacion del dinucleotido de adenina (7).
Devido ao fato dessa organela nao ter um sistema organizado de membranas em sementes secas e no inicio do processo de embebicao, a recuperacao estrutural comeca a ocorrer a medida que a hidratacao prossegue, tornando-se mais eficiente na fosforilacao oxidativa (Castro e Hilhorst, 2004).
Assim, ha necessidade de que o produto penetre na planta, transloque e atinja a organela onde ira atuar.
