Definition of centrosome in English:
centrosome
noun ˈsɛntrəsəʊmˈsɛntrəˌsoʊm
Biology An organelle near the nucleus of a cell which contains the centrioles (in animal cells) and from which the spindle fibres develop in cell division.
Example sentencesExamples
- A legacy of these ancient symbiotic interactions is that eukaryotic cells continue to show tight links between nuclei, centrosomes and microtubules in the form of Cell Bodies.
- The astral microtubule arrays around the centrosomes, like the nuclei, are visible as areas that are largely devoid of yolk granules.
- In most animal cells, the centrosome contains a pair of centrioles, which consist of an array of microtubules.
- On one hand, angiosperm cells lack centrosomes as microtubule organizing centres and are missing the contractile ring which serves as a tool for cytokinesis in animal cells.
- At metaphase, centrosomes initiate the bipolar microtubule spindle.
Origin
Late 19th century: from Latin centrum (see centre) + Greek sōma 'body'.
