Key Points: Cytokinesis

  • Cytokinesis is the division of cytoplasm into two daughter cells after karyokinesis (nuclear division).
  • In animal cells, a furrow appears in the plasma membrane, deepens, and joins in the centre to divide the cytoplasm.
  • In plant cells, a cell plate forms in the centre and grows outward to meet the lateral walls, forming a new cell wall. The cell plate represents the middle lamella between two adjacent cells.
  • During cytokinesis, organelles like mitochondria and plastids are distributed between the two daughter cells.
  • In some organisms, karyokinesis is not followed by cytokinesis, resulting in a multinucleate condition called syncytium (e.g., liquid endosperm in coconut).
