Cytokinesis


 à  process of cytoplasmic division to form two daughter cells.
n  Different in animals and plants.
n  Animal cells, the cytoplasm contracts to pull the plasma membrane inwards, forming groove called a cleavage furrow
n  In plant cells, cytokinesis in cells is markedly different.
n  A cleavage furrow does not form. Instead, membrane-enclosed vesicle gather at a plant cell’s equator between the two nuclei.
n  Vesicle fuse to form a cell plate
