This is straight from my Biology textbook:

"Cytokinesis differs in animal and plant cells. In animal cells, the membrane forms a furrow, or trench, that is pulled inward by tiny filaments, like a drawstring. Gradually the membrane pinches closed, forming a separate cell around each nucleus.

During cytokinesis in plant cells, the membrane cannot pinchinward because of the cell wall. Instead, a cell plate forms between the two nuclei made by the Gogli apparatus, which supplies the new plasma membrane. A new wall then grows as cellulose and other materials are laid down."

Why does cytokinesis occur in most animal cells?

Cytokinesis is nothing but cell division. Cell division is an inevitable part of growth. It is also necessary to replace old and worn out cells, for healing wounds etc. Many of the processes of animal life and growth depends on cell multiplication. Most of the cells in the body get worn out after a time of operation. It is similar to the wear and tear that occurs in machines. Hence as these old cells have to be replaced by new new cells and growth has to continue, cytokinesis occurs in most animal cells.
