Early development of cell plate

Vesicles from Golgi system

Cell plate grows centrifugally

The cell wall originates late in mitosis (during telophase) when the cell plate is formed by the fusion of a large number of vesicles derived from Golgi dictyosomes. The vesicles fuse laterally in the equatorial plane, and a cell plate is formed which grows centrifugally. The cell plate is then transformed into middle lamella, and primary cell wall materials are deposited on each side of the plate.
