How does a plant cell accomplish cytokinesis
pychu [463]

Answer:Cytokinesis in plant cells involves plants using spindle structures called phragmoplasts to carry vesicles of the cell wall material such as cellulose to the new cell plate. ... After the plate divides the plant cells into two daughter cells, the plasma membrane seals off and fully separates the two new cells. During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.
