Cytokinesis: The Key to Cell Division Success
What is cytokinesis and why is it essential for cell division?
a. Lines up the paired chromatids along the center of the cell in preparation for anaphase
b. Finishes mitosis by dividing the cytoplasm and organelles of the original parent cell into two separate daughter cells.
Answer:
Cytokinesis is the second part of the mitotic phase in which the cytoplasmic components of the cell are physically separated into two daughter cells. In animal cells, a contractile ring of actin filaments forms a cleavage furrow, dividing the original cell into two separate daughter cells.
Cytokinesis plays a crucial role in cell division as it completes the process by physically dividing the cytoplasm and organelles of the original parent cell into two separate daughter cells. Without cytokinesis, the cell would not be able to fully replicate and carry out its functions effectively.
During cytokinesis, a contractile ring composed of actin filaments forms just inside the plasma membrane of the cell. This ring contracts to create a cleavage furrow, eventually leading to the division of the original cell into two daughter cells. This process ensures that each daughter cell receives an equal share of cytoplasmic components and organelles, allowing them to function independently.
Overall, cytokinesis is essential for the successful completion of cell division and the generation of new cells. By understanding the importance of cytokinesis, researchers can gain valuable insights into the process of cell replication and its role in growth, development, and repair within living organisms.
