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. |
Binary Fission |
Fragmentation |
Binary fission is the asexual reproduction of a single-celled organism by division into two roughly equal parts. |
In fragmentation, the body of the organism simply breaks up into smaller pieces upon maturation. These pieces or fragments grow into new individuals. |
Occurs in unicellular organisms. |
Occurs in multi cellular organisms |
Example- Amoeba |
Example- Spirogyra |
