What is the difference between fragmentation and regeneration,
give any 2 differences ?

Fragmentation	Regeneration
1. Fragmentation occurs in multi-cellular organisms with simple body organisation.	1. Regeneration occurs in fully differentiated multi-cellular organisms with complex body organization.
2. In fragmentation, an organism breaks into pieces and each piece develops into new individual.	2. In regeneration organisms if breaks into pieces, each piece may or may not develop into new individual.
3. No specialised cells are involved in fragmentation.	3. In regeneration, specialised cells proliferate and form a mass of cells. The cells from the mass differentiate to form different cells types and tissues.
Example: Spirogyra	Example: Regeneration of blood cells in mammals.
