Solution

 

  Cytokinesis  Karyokinesis 
1 Cytokinesis is the division of the cytoplasm of cell. Karyokinesis is the division of the nucleus of a cell.
2 It occur at the end of M-phase, after the neculear division is over. It occur during M-Phase of cell cycle before cytokinesis begin to proceed.
3 Stages such as prophase, metaphase, anaphase, and telophase are not present in cytokinesis. It is divided into four stages: prophase, metaphase, anaphase, and telophase
