Cytokinesis

Cytokinesis (pronounced: /ˌsaɪtoʊkɪˈniːsɪs/) is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.

Etymology

The term "cytokinesis" is derived from the Greek words "kytos" meaning "cell" and "kinesis" meaning "movement".

Process

Cytokinesis begins after the cell nucleus has divided in mitosis or meiosis. The process is different in plant and animal cells. In animal cells, a cleavage furrow forms, and the cell membrane pinches inwards to form two separate cells. In plant cells, a cell plate forms along the line of division, which eventually develops into a new cell wall, separating the two new cells.

Related Terms

  • Mitosis: The process of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
  • Meiosis: A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell.
  • Cleavage furrow: The indentation of the cell's surface that begins the progression of cleavage, eventually leading to cytokinesis.
  • Cell plate: A plate that develops at the midpoint between the two groups of chromosomes in a dividing cell.
