Cytokinesis in terrestrial plants occurs by cell plate formation. This process entails the delivery of Golgi derived and endosomal vesicles carrying cell wall and cell membrane components to the plane of cell division and the subsequent fusion of these vesicles within this plate.

A cell plate is laid down duringa)Cytokinesisb)Interphasec)Karyokinesi...
Cytokinesis is the process of cell division that follows nuclear division (mitosis or meiosis). During cytokinesis, the cytoplasm of the parent cell is divided into two daughter cells, each with its own nucleus. The process of cytokinesis differs in animal and plant cells.
In animal cells, the cell membrane is drawn inward until the cytoplasm is pinched into two nearly equal parts. This process is called cleavage furrow formation. Eventually, the cleavage furrow reaches the center of the cell and the cell is divided in two.
In contrast, plant cells have a cell wall that cannot be drawn inward. Instead, a cell plate forms across the center of the cell. The cell plate is made of vesicles produced by the Golgi apparatus. These vesicles contain cell wall materials such as cellulose and pectin. The vesicles fuse together to form a flattened sac, which gradually expands outward until it reaches the side walls of the parent cell. Eventually, the cell plate divides the cytoplasm of the parent cell into two daughter cells, each with its own nucleus.
Therefore, a cell plate is laid down during cytokinesis in plant cells.
