Plant cells do not divided their cytoplasm by forming a furrow in cell membrane like animal cells rather they divide by cell plate because

1. Plant cell do not have centrioles
2. Cell wall formation beings with formation of cell plate
3. Cell plate represents middle lamella between the walls of two adjacent cells
4. Plant cells are enclosed by a relatively inextensible wall
