Anchor the ER, Golgi complex, lysosomes, secretory vesicles and some mitochondria. Provide tracks for vesicles to move from the cell interior to the plasma membrane and back. / Anker die ER, Golgi kompleks, lysosome, sekretoriese vesikels en sommige mitochondria. Voorsien spore vir vesikels om van die binnekant van die sel na die plasmamembraan en terug te beweeg.

Their main function is to maintain the shape of the cell and provide tensile strength. In animal epithelial cells, the nucleus is held in position by a basket shaped network of IFs made of keratin units. / Hul hooffunksie is om die vorm van die sel te handhaaf en trek sterkte te bied. In die epiteel selle van diere word die kern in posisie gehou deur 'n mandjie-vormige netwerk van IF's gemaak uit keratien eenhede.

Transport nutrients, proteins and organelles in animal and plant cells. Responsible for dividing the cytoplasm in cell division. Responsible for amoeboid movement. / Vervoer voedingstowwe, proteïene en organelle in diere- en plantselle. Verantwoordelik vir die verdeling van die sitoplasma in seldeling. Verantwoordelik vir amoebiese beweging.
