Based on what I've searched, fission is when a unicellular organism divides into 2 daughter cells (so it's basically like continuous division by 2) while fragmentation is when a multicellular organism forms another organism after the broken fragment from the parent cell. In my book and other sources, flatworms undergo fission but there are other sources that says they undergo fragmentation. Questions:

1. Can someone help me the real method of asexual reproduction the flatworms undergo?!
2. And would someone please explain the difference between the 2 methods in the simplest way?
3. Also, please compare regeneration to the two.

It would also be helpful if you could provide examples for each method.

Generally all flatworms are hermaphroditic, meaning an individual flatworm has both male and female reproductive components. They engage in sexual and asexual reproduction, with the dominant mode of reproduction varying among species. Asexually, flatworms procreate via fragmentation and budding.

Asexually, flatworms procreate via fragmentation and budding. Fragmentation, also called cloning, occurs when a flatworm splits off a part of its body, allowing the separated portion to regenerate into a new worm. With budding, a flatworm grows an extension from its body.
