Question

what is the defrence between regeneration and fregmentation

Answer 1

Fragmentation is when an organism is split into fragments, and each fragment grows into complete, individual organisms that are clones of the original organism.

Regeneration is the process of regrowth that organisms that allows for partial or complete regrowth of tissue after a damaging event.

The difference is that fragmentation specifies two parts each growing into complete organisms, but regeneration is simply a general process of regrowth. Few species are capable of fragmentation, but ALL species undergo regeneration, to varying degrees.

Answer 2

Fragmentation:
1. This occurs in multicelluar organisms with simple body organisation.
2. In fragmentation, an organism breaks into pieces and each piece develops into a new individual.
3. No specialised cells are involved in fragmentation.
4. Example: Spirogyra.

Regeneration:
1. This occurs in fully differentiated multicelluar organism with complex body organisation.
2. In regeneration, organism breaks into pieces, each piece may or may not develop into a new individual.
3. In regeneration, specialised cell proliferate and form mass of cells. The cells form the new differentiate to form different cell type and tissue.
4. Example: Regeneration of blood cell in mammals, tails in lizards.

Learn it in a tabular form, it would be easy.

Hope this helps you buddy!
