Fragmentation

Definition

Fragmentation is a form of asexual reproduction where an organism breaks into two or more parts, each capable of growing into a new individual. It is commonly observed in certain animals and plants.

5 Must Know Facts For Your Next Test

1. Fragmentation is common in sponges and some cnidarians like sea anemones.
2. Each fragment must contain part of the parent organism's central disk to regenerate completely.
3. Fragmentation allows for rapid population growth in stable environments.
4. It does not involve genetic recombination, so offspring are genetically identical to the parent.
5. Environmental factors such as water currents can aid in the distribution of fragments.
