During cytokinesis, the cytoplasm (the liquid center of the cell that holds the organelles into place) splits into two equal halves, and the cell becomes two daughter cells. This occurs right after the beginning of anaphase (in mitosis and in meiosis I and II).
Cell division continues during telophase (in mitosis and in meiosis I and II) until the cell has completely divided. mitosis and meiosis II starts again after cytokinesis. A new and complete nucleus has been formed in each of the two cells.
Cytokinesis in plants[change | change source]
When the cytoplasm and organelles are divided evenly between the two new cells, the plate then becomes less flimsy and soon becomes another cell wall separating the daughter cells. Cytokinesis splits the cell wall, unlike animal cells, where it splits the cytoplasm. The cell wall grows later as the two new cells expand.
