How does mitosis differ between the onion root and the roundworm or white fish blastula?

The only difference between vegetal (onion) cells and animal (roundworm) is not quite in mitosis, but in citokinese (not a mitosis phase since mitosis refers to nucleus division). Vegetal cells have a thick wall rouding the cell which needs different means to split than the membrane im animal cells.

The answer your looking for is a food chain grid. it describes how nature can support itself and survival of the fittest comes into play..
