Describe fragmentation in the planarian

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.
