A planarian can grow back its head because it has lots of undifferentiated stem cells all throughout its bodyGroup of answer choicesTrueFalse PreviousNext

Answer: True

Planarians possess a remarkable ability to regenerate, including the capability to regrow their heads. This regenerative capacity is largely attributed to the presence of a high number of undifferentiated stem cells, known as neoblasts. These stem cells are dispersed throughout the body of the planarian and serve as a pool for regeneration. When a planarian is cut or loses a part of its body, these neoblasts can proliferate and differentiate into the various cell types needed to reconstruct the lost structures, including the head. This ability makes planarians a valuable subject for studies in regeneration and developmental biology.
