Cytokinesis (Leaving Cert Biology): Flashcards

Final stage of cell division where cytoplasm divides into 2 cells

Immediately after mitosis is complete

Same number of identical chromosomes as parent cell

Approx. half of organelles & biomolecules from parent

Mitosis: chromosome separation; Cytokinesis: cell division

Cleavage - cleavage furrow pinches cell inward

Shallow groove that pinches cell membrane inward to split cell

At position of cell's equator during metaphase

Rigid cell walls prevent cleavage furrow formation

Cell plate (formed from vesicles)

Materials, primarily cellulose, for new cell walls

Animal: furrow pinches in; Plant: cell plate builds outward
