Introduction

In the process of mitosis, two important processes take place: karyokinesis and cytokinesis. Many people often confuse these terms and therefore it is important to understand what the difference is.

Karyokinesis

Karyokinesis is the process of division of the cell nucleus, in which the genetic material is divided equally into two daughter cells. This process It is divided into several phases. First is prophase, in which chromatin condensation occurs to form chromosomes. Then, in metaphase, the chromosomes line up at the equator of the cell and prepare for the next step.

• Prophase
• Metaphase
• Anaphase
• Telophase

Cytokinesis

On the other hand, cytokinesis is the process of division of the cell cytoplasm that occurs after karyokinesis. In this process, the cell divides into two completely separate daughter cells. It is important to note that in cytokinesis the separation of the genetic material does not occur, but rather the cytoplasm and the organelles contained in the cell are separated.

animal cytokinesis

Regarding cytokinesis, there is a small difference between the processes in animal cells and plant cells. In the case of animal cells, a constriction occurs in the center of the cell leading to the formation of a fissure. In this way, the cell divides into two daughter cells.

plant cytokinesis

On the other hand, in the case of plant cells, cytokinesis does not occur through strangulation of the cell, but rather a cell sheet is produced that forms in the middle region of the dividing cell. This sheet thickens and will end up dividing the cell into two daughter cells. It is important to mention that in this case the formation of a new cellular wall in the daughter cell.

Conclusion

In conclusion, while karyokinesis refers to the division of genetic material, cytokinesis refers to the division of the cell cytoplasm. Although these processes often occur simultaneously, it is important to understand their difference.

Remember that karyokinesis has to do with the genetic material, while cytokinesis has to do with the rest of the cell. Make sure you always remember this difference!
