Yes, the source of regeneration in Planaria is located centrally in the body. Planaria have a unique ability to regenerate complete organisms from fragments of their bodies, and this process is mainly controlled by a group of undifferentiated cells called neoblasts, which are located in the central body region known as the "head" or "trunk." The neoblasts are responsible for producing new cells that can differentiate and regenerate various tissues and organs.
