What is the main difference between Fragmentation and regeneration?

in fragmentation, an unicellular organism divides in certain fragments n each fragment develops into a new individual which is identical to its parents .
actually, regeneration is not a mode of reproduction but it is a simple process of regrowth . in regeneration , certain specialised cells are present which are responsible for the regrowth of the part that has been cut .
another main point is that in fragmentation the organism itself breaks into fragments but in regeneration the organism has to be cut and the fragment only regenerates if it contains the specialised cells.
For eg: in lizard , when the tail is cut , it regenerates to form new tail . this means that tail contains regenerative cells . but if u cut its head it will not regenerate because doesn't contain regenerative cells.
HOPE THIS HELPS . I HAVE TRIED TO EXPLAIN

PLZZ MARK IT AS BRAINLIEST IF ANSWER IS UPTO THE MARK
Fragmentation:this type of reproduction occurs in multicellular organisms with simple body organisation as in algae. Here the filaments break into parts and each part grows into a new individual. Regeneration: multicellular, fully differentiated organisms like hydra and planaria have the capacity to regenerate full body from a part of their body. This is known as regeneration.
How to mark it as brainliest?
i guess only the one who asked this ques can do that
Ok

FRAGMENTATION :
During this process the body of an organism split into fragments upon maturation , and each fragment grows into a new organisms which is a clone of the original one .
For example : Spirogyra
REGENERATION :
Mainly fully differentiated organisms have the ability to give rise to new individual organisms from their body part . That is , if the body of the organism is somehow broken or cut into many pieces , many of these pieces grow into separate individuals .
example : Planaria .
This process is carried out by specialized cells, which proliferate and make large no.of cells. From this mass no.of cells , different cells undergo changes to become various cells type tissues.
