Cytokinesis - Cell Division

Question	Answer
Cytokinesis	Occurs immediately after mitosis Cell Division
Cytoplasm during cytokinesis	splits into two equal halves
Cytokinesis occurance	beginning of anaphase and continues during telophase until the cell has completely divided and interphase has re-started
Cytokinesis in animal cells and plant cells	Very different process
cleavage	Cytokinesis occurs in animals by this process
Cleavage Furrow	The shallow groove that appears around the cell lining on the cell equator
Factors involved in initiating and regulating cytokinesis	Myosin II Actin ATP
Myosin II and Actin	Make up the contractile ring
Ingress	Inward movement
Continued ATP hydrolysis	Causes ingress
Abscission	Physical division of the two daughter cells
Plant cell wall in cytokinesis	Prevents cleavage furrow from forming
Vesicles	small membrane enclosed sac gather in the area between the two nuclei in plant cells
Structure formed from vesicles	Cell Plate
Middle lamella	Region formed between the two daugther plant cells
Timing of cytokinesis	Ensure sister chromatids separate during anaphase
