As mitosis completes cytokinesis is well underway. In animal cells, the cell pinches inward where the imaginary line used to be, (the pinching of the cell membrane to form the two daughter cells is called cleavage furrow) separating the two developing nuclei. In plant cells, the daughter cells will construct a new dividing cell wall between each other. Eventually, the mother cell will be split in half, giving rise to two daughter cells, each with an equivalent and complete copy of the original genome
In plant cells only, prophase is preceded by a preprophase stage. In highly vacuolated plant cells, the nucleus has to migrate into the center of the cell before mitosis can begin. This is achieved through the formation of a phragmosome, a transverse sheet of cytoplasm that bisects the cell along the future plane of cell division. In addition to phragmosome formation, preprophase is characterized by the formation of a ring of microtubules and actin filaments (called preprophase band) underneath the plasmamembrane around the equatorial plane of the future mitotic spindle and predicting the position of cell plate fusion during telophase. The cells of higher plants (such as the flowering plants) lack centrioles. Instead, spindle microtubules aggregate on the surface of the nuclear envelope during prophase. The preprophase band disappears during nuclear envelope disassembly and spindle formation in prometaphase

I only know of one difference that is the formation of cell plate for plant mitosis but not in animal cells.

plant cell hasa cell wall, central vacuole and chloroplasts, animal cell has just the plasma membrane, so duz the plant cell, but its got that wall, and multiple vacuoles, unlike the plants, and no chloroplats, hope that helps
