Fragmentation in planarians refers to their ability to regenerate lost body parts after being cut into pieces. This process allows them to develop into new individuals from fragments, with each piece capable of regenerating a complete organism. Planarians possess a high concentration of pluripotent stem cells, which play a crucial role in regeneration by differentiating into various cell types needed for tissue and organ formation. This remarkable ability makes planarians a popular subject for studies on regeneration and developmental Biology.

What type of flatworms undergo fragmentation?

Planarians, a type of flatworm belonging to the class Turbellaria, are known to undergo fragmentation as a means of asexual reproduction. When a planarian is cut into pieces, each fragment can regenerate into a complete organism, provided that certain body parts, such as a portion of the head and some regenerative cells, are present. This remarkable regenerative ability allows them to reproduce rapidly and adapt to their environments.
