Answer:

plant cell

Explanation:

The Golgi apparatus is a cell organelle responsible for modifying, sorting and packaging proteins and lipid molecules into vesicles (i.e., Golgi vesicles) for their delivery to targeted cell sites. A plant cell can contain many -even hundreds- of Golgi apparatus. During cell division of plant cells, Golgi vesicles combine at the metaphase plate in order to form a structure called phragmoplast. Subsequently, the cell plate formed by phragmoplast vesicles grows from the center to the cell walls. Finally, the vesicle membranes fuse to form a plasma membrane that divides the plant cell into two cells.
