Solution

Regeneration is a form of asexual reproduction. It is the ability of a simple organism to re-grow its lost parts.
Planaria can be cut into pieces, and each piece can regenerate into a complete organism. Cells at the location of the wound site proliferate to form a blastema that will differentiate into new tissues and regenerate the missing parts of the piece of the cut planaria.
