cytokinesis

 [si″to-kĭ-ne´sis]
the division of the cytoplasm between daughter cells in mitosis or meiosis.

cy·to·ki·ne·sis

(sī'tō-ki-nē'sis),
Changes occurring in the cytoplasm of the cell outside the nucleus during cell division.
Synonym(s): cytodieresis
[cyto- + G. kinēsis, movement]

cytokinesis

/cy·to·ki·ne·sis/ (si″to-ki-ne´sis) the division of the cytoplasm during the division of eukaryotic cells.

cytokinesis

(sī′tō-kə-nē′sĭs, -kī-)
n.
The division of the cytoplasm of a cell following the division of the nucleus.

cy′to·ki·net′ic (-nĕt′ĭk) adj.

cytokinesis

[sī′tōkinē′sis, -kīnē′sis]
Etymology: Gk, kytos + kinesis, movement
the division of the cytoplasm, exclusive of nuclear division, that occurs during the final stages of mitosis and meiosis to form daughter cells. See also karyokinesis. cytokinetic, adj.

cy·to·ki·ne·sis

(sī'tō-ki-nē'sis)
Changes occurring in the protoplasm of the cell outside the nucleus during cell division.
[cyto- + G. kinēsis, movement]

cytokinesis

a part of CELL DIVISION that usually occurs during TELOPHASE of nuclear division. The cytoplasm becomes divided into two parts which are sometimes unequal, e.g. the production of ova and polar bodies during OOGENESIS. The mode of splitting differs between organisms. In higher plants, a special membrane-producing area (the CELL PLATE) develops internally and becomes joined to the outer membrane; in lower plants, the cell wall and plasma membrane grow in from outside; in animals, the plasma membrane forms a deep cleft from the outside inwards which eventually divides the cell.

cytokinesis
