Question

Distinguish cytokinesis from karyokinesis.

Answer 1

Hint: Cells undergo karyokinesis and cytokinesis during cell division. The division can either be mitotic or meiotic. The word kinesis means movement which can be the movement of the cytoplasm or the nucleus. In mitosis, cells undergo cytoplasmic division which leads to the production of two daughter cells. In meiosis, the cell produces four daughter cells.

Complete answer:
Karyokinesis is the partition of the parent cell’s nucleus into two genetically identical daughter nuclei.
Cytokinesis is the division of the parent cell’s cytoplasm in the cell cycle. During this phase, the cell’s cytoplasm and the cell organelles divide equally into two daughter cells.

KARYOKINESIS	CYTOKINESIS
The process by which the nucleus of the parent cells divides to form two daughter cell nuclei is known as karyokinesis.	The process by which the cytoplasm of the parent cell divides into two daughter cells is known as cytokinesis.
Metaphase is the stage of the initial step.	Metaphase is the second step of the process.
Identical nuclei are formed	Cell membrane and the organelles of the cell divide equally into two cells.
Karyokinesis does not depend on cytokinesis.	Cytokinesis depends on karyokinesis.

Note: The process of cytokinesis starts in the Anaphase and is followed by Telophase. Karyokinesis can occur without cytokinesis but cytokinesis cannot occur without karyokinesis. Moreover, cytokinesis in plant cells is significantly different from that of animal cells. The plant cells have a cell plate formation which initiates from the cell wall and moves to the center. Whereas in animal cells the furrowing starts from the center and moves to the two sides.
