Answer
Planaria reproduces by regeneration. It is because they have specialised cells. These cells proliferate and make large numbers of cells. From this mass of cells, different cells undergo changes to become various cell types and tissues. Thus, different parts develop to make complete organisms.
Hydra is other organism which can also reproduce by the same process.
