Question

Distinguish between cytokinesis in plant and animal cell.

Answer 1

Cytokinesis in a plant:-

1. Cleavage cytokinesis occurs only in lower plants. Higher plants cells show cell plate cytokinesis.

2. The middle part of spindle persists during cytokinesis. It forms a complex called phragmoplast.

3. A mid-body is absent.

4. A row of vesicles develops in the equatorial plane in plant cell cytokinesis. 5. Vesicles fuse to form cell plate.

6. There is little role of microfilaments in plants cell cytokinesis.

7. It starts with the formation of cell plate during telophase.

8. The cell plate grows from the centre towards the lateral walls. So it is described as centrifugal.

9. Wall formation occurs in the region of cytokinesis.

Cytokinesis in an animal cell:-

1. It occurs through cleavage.

2. Spindle degenerates during cytokinesis.

3. A mid-body develops centrally

4. A row of vesicles does not form in animal cell cytokinesis.

5. A cell plate is not formed.

6. Microfilaments are actively involved in animal cell cytokinesis.
