Biology · CELL CYCLE AND CELL DIVISION

How does plant cytokinesis fundamentally differ from animal cytokinesis in terms of precursor structure and direction of wall/furrow formation?

1. A
   Plant: Cleavage furrow grows inward centripetally; Animal: Cell-plate grows centrifugally
2. B
   Plant: Cell-plate forms at centre and grows outward centrifugally; Animal: Furrow appears in plasma membrane and deepens centripetally
3. C
   Plant: Middle lamella breaks down outward; Animal: Aster microfilaments polymerize outward
4. D
   Plant: Contractile ring constricts from outside inward; Animal: Phragmoplast deposits callose from inside outward
