Fragmentation

Fragmentation

The breaking up of a body of a simple multicellular organism into two or more pieces on maturing, each of which grows to form a complete new organism is called fragmentation.

For Example: Spirogyra (a green filamentous algae plant found in ponds, lakes etc.),
sea anemones (marine animal)

The filament simply breaks into two or more fragments on maturation and each fragment grows into new spirogyra.

All multicellular organism can not reproduce by this method because random increase in number of cells, organisation into tissue and then organs is not practical.
