How is cytokinesis different in plant cells as compared to the animal cells?

Difficulty: Medium

Cytokinesis in Animal Cells:

Cytokinesis is the division of the cytoplasm. In animal cells, cytokinesis occurs by a process known as cleavage. A cleavage furrow develops where the metaphase plate used to be. At the site of the furrow, the cytoplasm has a ring of microfilaments (a part of the cytoskeleton). The ring contracts deepening the furrow and eventually pinching the parent cell into two.

Cytokinesis in Plant Cells:

Cytokinesis in plant cells occurs differently. Vesicles derived from the Golgi apparatus move to the middle of the cell and fuse to form a membrane-bounded disc called the cell plate or phragmoplast. The plate grows outward and more vesicles fuse with it. Finally, the membranes of the cell plate fuse with the plasma membrane, and its contents join the parental cell wall. The result is two daughter cells, each bounded by its plasma membrane and cell wall.
