Organizing centers for microtubules
Witryna13 lis 2015 · Centrioles. Found only in animal cells, these paired organelles are typically located together near the nucleus in the centrosome, a granular mass that serves as an organizing center for microtubules. Within the centrosome, the centrioles are positioned so that they are at right angles to each other, as illustrated in Figure 1. WitrynaThe organization of microtubule networks is crucial for controlling chromosome segregation during cell division, for positioning and transport of different organelles, and for cell polarity and morphogenesis. The geometry of microtubule arrays strongly depends on the localization and activity of the sites where microtubules are …

WitrynaThe organization of microtubules into ordered arrays is essential for cell division and differentiation. Centrosomes have long been recognized as major components of this process in metazoans. Most plant cells, however, do not have such morphologically distinct organelles, although they do have functionally equivalent microtubule … Witryna31 sie 2024 · Microtubules Give Structure to Cilia and Flagellum. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. The male sperm cell for example, has a long tail that helps it reach its desired destination, the female ovum. Called a flagellum (the plural is flagella ...
