Final answer:
Cytokinesis differs in plants and animals, wherein animal cells form an actin ring leading to a cleavage furrow and separation, while plant cells form a cell plate that results in two new cells with distinct cell walls.
Step-by-step explanation:
Cytokinesis differs in plant and animal cells in terms of the mechanisms involved in physically separating the newly formed daughter cells. In animal cells, cytokinesis occurs through the formation of an actin ring that constricts the cell's cytoplasm, resulting in a cleavage furrow that pinches the cell into two separate daughter cells. In plant cells, however, a structure called a cell plate forms at the site of division, which grows outwards to meet the cell walls, eventually leading to the formation of new plasma membranes and cell walls for each of the two daughter cells.
