How does cytokinesis in plant cells differ from that in animal cells?
|
Cytokinesis in plant cells |
Cytokinesis is animal cells |
|
|
The division of the cytoplasm takes place by cell plate formation. |
(i) |
The division of the cytoplasm takes place by cell furrow method. |

Cell plate formation starts at the centre of the cell and grows outward, toward the lateral walls. |
(ii) |
Furrow starts at the periphery and then moves inward, dividing the cell into two parts. |
