I would think that the major difference would be that plant cells have a cell wall in addition to a cell membrane.

Hmm.. here is what I found at the first link below:
The separation of daughter cells from each other is a process known as cytokinesis, and is separate from mitosis. In cytokinesis, animal and plant cells differ considerably from each other. These differences are the consequence of having or not having a cell wall.
-----------------------------------------
So - it would appear that mitosis itself is not different for plant and animal cells, but cytokenisis is.

============================
Here is what I found at the second link below:
Cytokinesis
The physical partitioning of a plant or animal cell into two daughter cells during cell reproduction. There are two modes of cytokinesis: by a constriction (the cleavage furrow in animal cells and some plant cells) or from within by an expanding cell plate (the phragmoplast of many plant cells). In either mode, cytokinesis requires only a few minutes, beginning at variable times after the segregation of chromosomes during mitosis (nuclear division). In the vast majority of cases the resulting daughter cells are completely separated. Since they are necessarily smaller cells as a result of cytokinesis, most cells grow in volume between divisions.

-----------------------------------------
The key distinctions seems to be that animal cells separate by cleavage and most plant cells separate by growing a cell plate.

I don't think so that there is an much difference between mitosis in an animal and a plant cell.
The nuclear and chromosomosomal events of mitosis in plant cells are same as those in animal cells.But some diffrences are as follows
1.in the plant cell there is no centrosome(centriol)and the aster(star like figures at opposite poles) are not formed but spindle formation still occures formed by cytoplasmic strands(microtubules).
2.in telophase of the plant cells the cytoplasm dose not constrict(furrow is not formed).Instead,a cell plate or a new cell wall is laid downin the cytoplasm at the equatorial plain of the spindle.It grows center to periphery,thus dividing the original cell into two daughter cells

Besides cytokinesis there are differences. Two of the most striking are that plant cells do not have centrioles, but do have PPBs. Centrioles are the structure from which the mitotic spindle fibers arise and attach to the centrosome. It has been widely assumed that the centrioles are required for organization of the spindle however, this appears not to be true. Mitosis proceeds even when the centrioles are destroyed. The true function of the centriole is not known. In additon to lack of centrioles, plant make a structure called the preprophase band (PPB). This is a band of actin and microtubules that encircles the cell in the same position that the new wall will form during cytokinesis. The exact function of the PPB is unknown, but it is believed to somehow mark the cortex so that the phragmoplast (also plant specific) that forms during cytokinesis is in the correct position.

How does mitosis in plant cells differ from that in animal cells?
