At which point in mitosis does a cleavage furrow form?

In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division.

a cleavage furrow is not found in plant cells. In cytokinesis, animal cells form a cleavage furrow to divide the cells: ... However, in plants, something different forms: A cell plate is a barrier that forms between 2 dividing plant cells and eventually becomes the new cell wall that separates the 2 new cells.
