Question

Differentiate between regeneration in lizard and planaria

Answer 1

Regeneration is a modified form of

fragmentation. It is known as a process that makes genomes, cells

organs, organisms, and ecosystems resilient after disturbances or

damage. Every species living on earth can regenerate, but only a few

species use it as an asexual reproduction method, thus producing new

individuals by their body parts.

Planarian flatworms are highly adapted

with regeneration capabilities because of their asexual reproduction

method. Among the vertebrates, tailed amphibian (Salamanders and newts)

and certain lizards (geckos) are highly adapted to regenerate their

limbs, tails, jaws, eyes and certain internal organs. As they are more

complex multicellular animals, they cannot use regeneration to reproduce

 or as an asexual reproduction method. Star fishes also have the same

ability to regenerate their arm, but unlike tailed amphibians and

lizards, lost arms of star fishes could regenerate a complete new

organism.

Answer 2

IN THE REGENERATION OF PLANARIA

1) IF WE CUTTED THE PLANARIA INTO MANY PIECES , THEN THE PECIES CAN GROW INTO A NEW INDIVIDUAL

2)BUT IN LIZARD, IF WE CUT THE TAIL IT WOULD REGENERATE AND GROW INTO A FULL TAIL
