1.Fragmentation occurs in plants whereas regeneration occurs in animals
2.only few species of multicellular organism undergo fragmentation whereas many organism can regenerate
1.Fragmentation occur in multicellular organism with simple body organisation i.e.plants whereas regeneration occurs in multicellular organism with well differentiated body i.e. animals.
2.in multicellular organism specialised cells are arranged in specialised organ.in such a carefully organised situaion
Cell by cell division would be impractical.Thus few multicellular organism undergos fermentation whereas regeneration is carried out by specialised cellwhich proliferate and make large number of cell.from this group of cell different cells undergo changes to become various tissue thus makes regeneration possible
