Which type of regeneration is characterized by the remodeling of existing tissues into new structures without significant cell proliferation?
Show answer and explanation
Correct answer: Morphallaxis
Morphallaxis, famously observed in Hydra, involves the reorganization of existing cells into a smaller version of the organism. In contrast, epimorphosis relies heavily on new cell division and blastema formation.
