The document studies the dynamics of the Golgi apparatus in root cells of Triticum aestivum during cell division, focusing on the role of microtubules in maintaining Golgi localization. It explores the ultrastructure of Golgi stacks and their behavior during different phases of the cell cycle, demonstrating their continued function in producing cell wall compounds essential for cytokinesis. The research highlights that Golgi apparatus divides into vesicles that are transported along microtubules during cell division.
