In plant cells, instead of a cleavage furrow, a cell plate forms down the middle of the cell, separating it into two daughter cells. 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 plane.
After formation of an early tubulo-vesicular network at the center of the cell, the initially labile cell plate consolidates into a tubular network and eventually a fenestrated sheet. The cell plate grows outward from the center of the cell to the parental plasma membrane with which it will fuse, thus completing cell division. Formation and growth of the cell plate is dependent upon the phragmoplast, which is required for proper targeting of Golgi-derived vesicles to the cell plate.
As the cell plate matures in the central part of the cell, the phragmoplast disassembles in this region and new elements are added on its outside. This process leads to a steady expansion of the phragmoplast, and concomitantly, to a continuous retargeting of Golgi-derived vesicles to the growing edge of the cell plate. Once the cell plate reaches and fuses with the plasma membrane the phragmoplast disappears.
This event not only marks the separation of the two daughter cells, but also initiates a range of biochemical modifications that transform the callose-rich, flexible cell plate into a cellulose-rich, stiff primary cell wall.
The heavy dependence of cell plate formation on active Golgi stacks explains why plant cells, unlike mammalian cells, do not disassemble their secretion machinery during cell division.

Cell plate
In animal cells, cytokinesis occurs by a process called cleavage. The first sign of cleavage is the appearance of of a Cleavage furrow.
they aid basic cell movement and cell contraction as well as enabling the cell to divide
forming a cleavage furrow that pinches the cell into two
The cell membrane creates a cleavage furrow in animal cells, pinching the original (mother) cell in to two pieces. New cell walls are constructed at the midline of the original cell in plant cells.
An animal cell's structure is flexiable while a plants cell's structure is rigid
Animal cells!
Micro filaments form the cleavage furrow.Ring of filaments lay in the equator of the cell and its contraction forms the cleavage.
The Cleavage FurrowCleavage furrow involve in cytokinesis. Centrioles are found only in animals

Cytokenesis in plant cells divide with a cell plate, that will later form the cell wall structure of the plant cell. In animal cells, a cleavage furrow forms and splits the cell membranes.

that the animal once had a use for that structure depending on where it lived. or that it decended from an animal that had that structure and used it.
In the m-phase the cytoplasm is split by a cleavage furrow.
