- Fragmentation involves the breaking up of body filaments into two or more small parts called fragments.
- Each fragment undergoes intercalary cell division (mitosis) and forms a new individual.
- Mitosis is a type of cell division which involves the formation of daughter cells with the same number of chromosomes as in the parent cell.
