Cytokinesis in animal cell and plant cell respectively occurs by

NCERT CLASS-XI – Page No. 166.

Mitosis accomplishes not only the segregation of duplicated chromosomes into daughter nuclei (karyokinesis), but the cell itself is divided into two daughter cells by the separation of cytoplasm called cytokinesis at the end of which cell division gets completed.

In an animal cell, this is achieved by the appearance of a furrow in the plasma membrane. The furrow gradually deepens and ultimately joins in the centre, dividing the cell cytoplasm into two.
