WebIn animals, cytokinesis is centripetal. In animal cells, cytokinesis is accomplished by furrow formation which starts from the cell membrane. In this process cleavage of cytoplasm takes place. Thus, in animal cells, cytokinesis starts from the periphery and moves towards the centre, i.e., centripetal. So, the correct answer is ' Centripetal'.
