The plant cells undergo the same stages of mitosis as in animal cells but different in cytokinesis. Which of the following is true about cytokinesis which occurs in plant cells?
The vesicles is form by actin filaments in cytoplasm
The vesicles assemble at equator between the two nuclei to form a cell plate
The cell plate grows until fuse with the plasma membrane to form cleavage furrow
The cleavage furrow helps divides the cell into two daughter cells.

I and II only
III and IV only
I, III and IV only
I, II, III and IV
