Solution:

In higher plants cytokinesis takes place by cell plate method. In this method small vesicles of Golgi complex are assembled at the equator. Here spindle persists for some time called phragmoplast. All vesicles fuse to form two sheets which enclose a matrix or film. This film becomes solidified to form cell plate or middle lamella. It grows centrifugally and finally comes in contact with lateral walls of parent cell. Now phragmoplast disappears. Cellulose, hemicellulose and pectin are deposited on either side of cell plate. It forms primary cell wall.
