In cells that lack a cell wall (animal cells), the cell pinches into two. In cells that have a cell wall (plant cells), a cell plate forms between the two new cells.

Cytokinesis in an animal cell occurs by a process called cleavage. A cleavage furrow appears and at the site of the cleavage furrow, the cytoplasm has a ring of microfilaments made of actin associated with molecules of the protein myosin. This ring of proteins will contract causing the furrow to deepen, which will then in turn pinch the cell into two separate cells.
In a plant cell, vesicles containing cell wall material collect at the middle of the parent cell. They will fuse and form a membranous cell plate. This plate will grow outward and it accumulates more cell wall material. Eventually the plate will fuse with the plasma membrane and the cell plates contents will join the parental cell wall. This results in two different daughter cells.
Cytokinesis is the division in two of the cytoplasm. It occurs near or after the end of nuclear division. In animals, the cell membrane folds in all around the cell. From the outside, the cell looks like a half-deflated balloon that has an invisible thread looped around it; as cytokinesis proceeds the thread is increasingly tightened. Really, the tightening is by protein fibers of the cytoskeleton, orientated in various directions just below the cell membrane. Plant cells cannot go through the same process, as the cell wall prevents changes to the cell's shape. Instead, the Golgi body manufactures a plate (middle lamella) of vesicles in a plane between the two daughter-nuclei. This plate spreads out from the center of the cell, eventually abutting against the cell membrane all round the cell in that plane. The cell then lays down a cell wall, replacing callose with cellulose and pectin. To see images, visit: animal

Because a plant cells are surrounded by the rigid cell wall, it cannot use microfilaments to go through cytokinesis. Instead, it builds a cell plate in the middle of the cell to represent the division.
An animal cell does not have this rigid structure, so it forms a cleavage furrow by pinching the cell in the middle with microfilaments. This will successfully divide the cell into two.
In the cytokinesis of plant cells, a cell plate forms from fragments of the cell wall and develop into a new cell wall, splitting the cell in two. In animal cells, a cleavage furrow forms from a series of microfilaments and contracts like the drawstring of a bag to split the cell.
In plants the cytokinesis takes place by cell plate formation and in animals it is mostly by furrowing of cytoplasm.
it has something to do with contraction
Plant cells do not have centrioles, whereas animal cells do. Plant cells form a cell plate between the two newly forming cells during cytokinesis, along which the cell wall will form, whereas animal cells do not.
Animals and plants are different because animals have one system of vessels and plants have two systems of vessels that aren't connected.
There is no longer any difference in the classification system of plants and animals. Before, it was that you would use the term division for classifying plants instead of phylum,used to classify animals. Now, phylum can be used to classify plants and animals.
The onion has easily observable chromosomes and the whitefish has a clear view of the spindle apparatus.
Cytokinesis is cell division and occurs right after mitosis, it is important in cell division in plants and animals.
In plants cytokinesis occurs by the formation of cell plate which takes place by centrifugal method while in animals it occurs by the formation of cleavage furrow which takes place by centripetal method.

What's the difference between eukaryote and prokaryote and animals and plants ?

In plants, a new cell wall forms to split the cell
Plant cells do not have centrioles, whereas animal cells do. Plant cells form a cell plate between the two newly forming cells during cytokinesis, along which the cell wall will form, whereas animal cells do not.
the difference is that animals feed on other plants and sometimes animals and flowers feed off the sun and water.
