Fragmentation

Definition

Fragmentation is a form of asexual reproduction where a parent organism splits into fragments, each capable of growing independently into a new organism. It is common among certain bacteria and fungi.

5 Must Know Facts For Your Next Test

1. Fragmentation involves the breaking down of the parent organism into multiple parts, each part developing into a complete organism.
2. This process does not require genetic recombination, making it faster than sexual reproduction.
3. Fragmentation is often observed in filamentous cyanobacteria and Actinomycetes.
4. Environmental factors such as nutrient availability and stress conditions can trigger fragmentation in microbes.
5. Each fragment must contain necessary cellular machinery to survive and replicate independently.
